Somewhere in Shibuya, Japan, Tsukino had a huge fascination with Japanese Urban Legends and mythological creatures, wishing that they were real. Due to her loneliness and has struggles finding friends, she wishes to have a legendary Japanese Monster or Spirit as her friend ever since she used to be a little girl, she used to have Urban Legendary Creatures as imaginary friends and the other kids used to think she was “weird” because of this, but now, she was 21. She was recently one of the citizens of Harajuku, one of the famous places in Japan, and she was one of the district’s Otakus. Despite her cute looks when it comes to being into Decora Kei fashion, she bottles her loneliness up in public by trying to stay positive and cheery while trying to blend in with the in-crowd.

Her coping mechanism was the Sonic the Hedgehog franchise, her favorite game since childhood. Tsukino has the goals and her wishes to become exactly like Sonic, her favorite game character. Tsukino has used her love for the Sonic franchise, most likely the Japanese side of the franchise, as her Comfort zone. She’s been tired of an endless loop of her loneliness and how she never fit in and wishes for something greater in her life and her goals to be like Sonic eversince…that was until the day, her wish would soon come true, but a twist of fate will soon change everything for Tsukino...

On an ordinary day, on an ordinary afternoon in Shibuya, Japan, Tsukino was sitting on a bench, watching an episode of Sonic X on her phone by herself, as she sniffled. She was wiping her tears after a long quiet cry hiding away, watching an episode of Sonic X anime. A group of Gyaru Girls, who were passing by her, then looked and stared at the introverted otaku as the group gossiped about her during that...

“Hey, has anyone seen Tsukino around here?” 

A Gyaru Girl with lavender clothes and yellow and purple dyes on her curly, tied up hair, was walking with the group.

“She's probably trying to hide her little face watching anime by herself like the weirdo she is!” 

Another Gyaru Girl with a Barbie-looking outfit with blonde hair and pink dyes with pink accessories on her hair said to one of the Gyarus, as multiple mean Gyaru Girls laughed together at Tsukino, as they walked past from her, as Tsukino cried a little more.

 “UGH! Hanako and her circle were such bitches…!” 

Tsukino said under her breath as she sniffled and paused the YouTube video, Tsukino wiped the tears from her eyes and said…

“I'm tired of this same loop left to right. *Sigh* I wish...I wish I could be like him; I Could be different...stronger...as stronger as an Oni…confident...heroic...Just like the Blue Blur…make everyone else respect me.... I wish I could just be...the fastest...yeah, I wish I could be...the fastest thing alive...”

Just then, a light blue glow magically manifested, and out came what appeared to be a Chao, a light blue and white Chao with a back head resembling Sonic spikes and a light red cross on the chest. The Chao was flying around in Shibuya and heard the cries and the wishes of a misfit Otaku girl. The Chao spoke in a child-like voice…

“Finally, I have found my companion with a purpose…”

“H-Huh?? Who said that…?”

Tsukino said as she stopped crying, though the tears are still in her eyes, as she looks both ways. But then she looked at what’s in front of her to see a floating Chao nearby on her face.

“Why, that would be from me, little miss.”

“A real Chao??”

“Why yes, I’m one of the Chaos, you can call me Nuggie.”

“Hi, Nuggie…?”

“I see those tears in your eyes, the long face, that sad tone of your voice…what seems to be the problem?”

“For long in my life, I was shy and meek in my life, trying to bottle up my emotions with positive thoughts in the public to hide my true feelings...I never seemed to truly fit in because of my struggles with finding friends and my introversion...I wanted to have a Legendary monster and spirit as a friend when I was a little girl, as I see them as imaginary friends as a coping alter and all of the other kids made fun of me because of that...And now, my day has come, and it's two of my goals and my wishes, all I ever wanted to be was like the blue blur, Sonic the Hedgehog, confident, heroic, and fasted, and as stronger, bigger, toughest as the spirit of the Oni. My wish was to be like both...both Sonic and the Oni…I need to make both of my wishes come true…”

“So, you wanted to be like Sonic and become an Oni at the same time, huh? Well, that wish could finally be your reality and I know where I can make it come true! Now, come and take my hand, will you?”

“Okay…?”

As the lonely Japanese girl then takes the Chao’s hand, Tsukino felt a magical spark in her hand as Nuggie magically teleported Tsukino and himself into… Oeyama. 

There they found themselves was one of the land’s legendary shrines, but it’s one of the lesser-known shrines a few may have found in Japan.

“W-Where are we…?”

“This is one of the shrines located in Oeyama, the Land of the Oni’s Legend. A few people including the Japanese know about this Shrine’s legend, and what was in it, was this Iron Club, belonging to the spirit of the Oni.”

“An Oni’s iron club?? What happens if I touch it, will it grant me special powers and the Oni’s spirit?”

“Of course, with this Iron Club you acquired, the spirit of the Oni and his special powers will awaken in you! So go on and take it, and soon, your wish will finally be granted! The Spirit of the Oni depends on you!”

As Nuggie motivates her…Tsukino’s expression went from shyness to confidence.

“I’ll do it for you, for the Oni’s Spirit.”

Tsukino may be introverted, but she's got a big, brave heart, as the Japanese Woman then bravely goes up to the steps of the stoned staircase, while heading to the shrine, everything outside here reminded of those Japanese Shrines from the old Japan era she remembered seeing them when she was a kid, and outside of the shrine has Oni statues nearby during her investigation. As Tsukino headed the shrine’s interior, the shrine was so huge just like the other big shrines in the historical Japanese era. There she saw was a big silver iron club, that club was so big it was covered in bandages with tan spikes everywhere, it reminded her of a baseball bat covered in nails.

“Well, this is it…”

Tsukino then said to herself as she came closer to the floating iron club, she could feel the glowing blue light shining on her that was coming from the club, as she headed towards it.

“Here goes nothing…”

Said Tsukino to herself as she gulped down her throat by herself, as her shaking arm slowly reaches towards the iron club and then…she grabbed it gently. One of her hands then gently touched the club and took it with two hands, it was so big and heavy, as heavy as a giant, silver baseball bat. Once she picked up and touched the Iron Club with two of her bare hands and in the matter of seconds, Tsukino suddenly started glowing dark blue, the Iron Club’s power had bought the Oni’s spirit in her and felt a powerful surge from her body, as she felt the Japanese Demon Spirit’s power and soul awakening and emerging inside of her. Tsukino was suddenly floating as she could feel the Oni’s power awakening inside of her, during the awakening power, reality started to warp and bend around her, she was in the blue void surrounded by magical bubbles.

“Huh?? What’s with all the magic sparkles and bubbles?? Am I in a Magical Girl Anime??”

Tsukino said to herself in the state of surprise by the reality warping caused by the Oni’s spirit awakening in her, dark blue wind surrounded her as she felt a tingling sensation but a magical transformation about to begin.

Tsukino felt pressure happening to both of her hands and arms, as her arms began to fuzz while her hands felt like Pins and Needles. Dark tan patches of fur started sprouting on both of her petite, feminine hands as they began to grow bigger, becoming strong and masculine, as the fur then spread from her hands to shoulders, both of her arms then expanded and bulked up with muscles as they grew bigger, body hair started growing on both of her arms. As she flexed her muscular arms, the dark blue fog surrounded her elbows and hands as bandages that expose her fingers magically manifested on her elbows and hands. 

The dark blue fur then sprouted on Tsukino's shoulders and backside, her spine arched into a masculine form as she grew spikes on her back one by one to the point where she grew a dark blue, hedgehog tail from her tailbone, the former hedgehog tail then peeked out of her jacket and skirt as it started wagging. Her shoulders then broadened and bulkened into its masculine status as both dark blue hairs then sprouted and grow from under her armpits.

Dark blue and dark tan fur sprouted on her torso as her jacket unbuttons by itself and tied itself up to her waistline as it magically morphed into a dark grayish yellow sweater. Tsukino felt her chest beginning to tingle while her stomach suddenly growled, both of her breasts magically shrink quickly into its flatness, and grew into a pair of strong, masculine pecs while her belly then magically expanded into a muscle gut, her shirt disintegrated along with her bra, exposing her muscle gut and pecs as a dark red cross scar formed from her chest to her stomach.

Tsukino's hips then quickly receded to her masculine status as she grew taller and bigger. The dark blue patches of fur then spread on her legs, both of Tsukino's legs grew a bit bigger and muscular as a tingling sensation happened to her feet, her shoes then started growing tighter and tighter, until they burst, revealing that her feet become dark blue, three-toed paws as she wiggled the six of her toes, the dark blue fog then appeared on her ankles to her feet as bandages then magically manifested on the legs. Old shoes disintegrated and magically reshaped into a pair of very dark red and grayish red boots with very dark red soles underneath that fits her new feet with her skirt glowing and magically morphing into a pair of dark blue, oversized pants as Tsukino then suddenly felt a tingling and rumbling sensation from her thighs…

BWOMPH~!

WOBBLE~

Tsukino's butt-size quickly grows and swells as her thighs become thicker, becoming about the size of her gut and fitting her oversized pants and waist-tied sweater. Dark blue fur then sprouted on her thighs and butt she jiggles and shake her huge butt and thick thighs, her feminine structure then turned masculine.

Tsukino felt an intense pressure in her groin, the dark blue and dark tan patches of fur then reached below the waistline and her crotch-area, the pain subsides to a weird but arousing sensation from between her thick thighs, she felt her womanhood growing outwards and changing, it was getting bigger. Her hormones, reproductive systems, and sex chromosomes were all swapped into the opposite gender, Tsukino blushed as a new bulge formed from below, rendering her as a male. His panties were getting tight, as they magically shifted into a pair of Fundoshi.

Both of Tsukino's ears began to fuzz as they grew pointy, earrings then fell out as dark blue and dark tan patches of fur grew, they've grown bigger as they moved upwards, becoming a pair of Hedgehog ears. The dark blue fur color then spread throughout his aqua dyed black hair, the accessories on his hair began to fall out one by one along with two ribbon hairties that were tied to his Odango buns, revealing his flowing hair. The dark blue colors then completely spread as his hair grew longer and hardened into quills resembling Sonic's spikes. Makeup began to vanish from his face, his eyes bulged and stretched outwards, his sceleras then turned black with his irises turning yellow and pupils about the same as his sceleras and even his eyelids becoming a very dark blue eye-shading. His nose then turned black and rounded as the dark tan grew on half of his face as it grew and stretched out, becoming animalistic, his teeth then grew into fangs with two of them from below growing sharper and monstrous, both eyebags formed from under his eyes, and he grew a short, demon-like horn from his forehead.

Tsukino's neck broadened and arched to its bulkened, masculine state, the dark blue patches of fur then spread on his neck as his vocal cords started to strain. A lump then grew from the inside of his throat, changing his Japanese, Anime girl-esque tone to a deep, masculine, and monstrous tone of voice though keeping his Japanese accent. Once his face finally grew into a muzzle of an anthropomorphic, masculine Mobian Hedgehog, his black and yellow eyes flashed open as he lets out an Oni-like roar in his new tone of voice...

“HHRRRAAAAAAARRGGGHH!!”

After the physical changes are done, the Iron Club from earlier appeared once again as the transformed Tsukino grabbed it with his strong, firm hand, and then strikes an awesome pose as the background flashes with an awesome Sega Genesis-styled SFX.

Reality went back to normal, as the fully and physically transformed Tsukino was back at the inside of his shrine with just an iron club in his hand.

“Wuh? What just happened--?”

Tsukino said in his new tone of voice, but when he noticed his change of voice, he then covered his mouth with his new hands. Tsukino then felt an Adam's Apple from the inside of his throat and realized that it gave him a new, masculine voice. He then saw his new, large hands and bandages, all the way through his muscular arms, Tsukino blushed as he flexed and squeezed his new arms. Tsukino then caresses his new ears while feeling the quills and the spikes from his back and a horn from his forehead and felt a masculine muzzle and sharp fangs. He then noticed that he has grown 7’3ft taller than his usual 5'0ft self and felt his grown belly as he pinches his muscle gut. 

Tsukino then saw a pair of pecs on his chest as he felt them to the point where he squeezes and caresses them, causing him to moan softly. Tsukino takes off his new shoes, only to find he has grown huge paws that are also covered by his bandages as he wiggled the six of his toes and puts his shoes back on afterwards. Tsukino noticed his huge butt and his thick thighs along with his wagging tail as he shakes and jiggles it, his tail noticeably wagging during that. Tsukino then felt his crotch became bloated, he gulped and sweated nervously as his face along with his ears blushed, as he placed the hand on his fully-grown bulge and then faced a shocking surprise that he's been turned into a Man.

“Did…Did that Iron Club really change me?? What’s going on?”

Said Tsukino at the state of shock and confusion, as he noticed an old Japanese mirror from nearby and looks right behind him. When he went to the old reflection in the mirror, looking at himself and noticed his fully changed self...he screamed in shock and surprise, as if he scared the hell out of himself.

“O-OH MY GOD!! Not only I’ve become a Man, but I also become a huge Oni in a form of a Hedgehog!”

Tsukino said in a tone of shock and confusion…but grew despondent about his physically changed self as his Hedgehog ears slowly went down.

“But…But I don’t understand this, I may now have this club while I have acquired the Oni’s power and spirit…I don’t know who I am…Is this the new me I’ve become…?”

“Hey, don’t feel too bad for yourself.”

Nuggie said to a despondent Tsukino as he comforted him, his ears went up again.

“Your wish has finally granted, and with this Iron Club, you have finally awakened and acquired the power and the spirit of the Oni, You're Tsume now!”

“Tsume?? Who’s Tsume?? Wait…Wait a minute…!”

Tsukino spoke in a state of confusion, but his confusion turned into realization as his mind started shifting away along with his old personality, former memories of himself as a Human faded and were replaced by his new, recent ones as himself, his eyes flashed open again during that.

“After all this time, I have realized something, I've finally found who I really am and myself too…I'm no longer a lonely, shy, meek, and introverted Japanese 21-year-old Human named Tsukino anymore, I am a 30000+ Year Old Male Oni that I was once a normal Oni who got transported into a game and met Sonic, I've got beaten by him, but I later grew fascinated and inspired by him so that I took the form of a Humanoid Hedgehog to be him, I have my heroic deeds but I'm really just a vigilante. I'm Funny, Charismatic, Rude, Clumsy, Certain, Friendly and Stubborn. I may be overprotective and slightly dangerous, but I'm a kind-hearted, sweet, yet a bit of a goofball…I-I…I really AM Tsume!”

He said as he has had completely forgotten his past as a Japanese Human Girl and has finally remembered who he is, a Heroic EXE, a Japanese oni who takes the form of an anthropomorphic Hedgehog called Tsume. Nuggie flies towards Tsume and gives him a warm hug and embrace and said…

“Welcome back, Tsume.”

And on this vary moment, since having forgotten his previous self as a former Otaku and a Harajuku citizen, Tsume has reunited with his companion Chao, Nuggie, as continues his moral things, though still having his fascination over Sonic. He uses his Iron Club he has recently reunited with, to hunt down evils and entities who troubled enough people though he can be anxious and nervous when it comes to his heroic actions and him being really a vigilante, he has a side of being a tough, killing machine and the other being a big sweetie though constantly shy and being a bit of a Tsundere. At least he's happy with not only with his newfound powers, but his new self.

THE END.
