"Mother? Can I have a garment like big sister?" A little boy asks
"Of course you can my child. It's going to take some time." A woman responds
A teenage boy arrives in Honnō City. He has medium length jet black hair that is pinned out of his face with bobby-pins while one hairpin is shaped like a sewing pin crossed over a needle. He wore a letterman jacket with pristine dark indigo jeans and a pair of sneakers with thick insulated soles. His blue eyes gleamed in the sunlight as he walked towards Honnouji Academy.
There must've a glitch within the system. A new transfer student has enrolled into Honnouji Academy but he has no personal information not even his name is listed. He is dressed similarly to the other newest transfer yet his appearance seems awfully familiar to the young woman as she stares at the computer screen.
"Who are you?" The young woman questioned within her subconscious
Meanwhile a young teenage girl with brown eyes and brown hair that is styled in a bowl cut launched herself at the new kid. She was caught by her friend as she sighed.
"Mako, you can't just launch yourself at every new person you see." A girl with a red streak in her hair sighs
"Huh?" Mako questions as she does a double-take
Mako's eyes widen as her jaw drops to see that the new kid wasn't her best friend.
"I'm sorry about her." The black-haired girl sighs
"Don't worry about it." The black-haired boy replies
"You're new here right?" Mako asks
"Yeah, just transferred today." The black-haired boy smiles
"Gotta name?" The black-haired girl questions
"It's Tatsuo, what's yours?" Tatsuo says
"I'm Ryūko." Ryūko introduces herself
"And I'm Mako Mankanshoku." Mako says with a big smile
Tatsuo had found himself a couple of friends within Honnōji Academy. He was a model student and often helped Ryūko battle against the other club presidents. His moves were fluid and flexible and his choice of weapons were his bare hands. The student council couldn't understand how a normal human was able to defeat Gokū Uniform enhanced club presidents with bare hands.
The next day, Satsuki confronts Ryūko in her Junketsu, overwhelming her with her new power and showing no shame in her appearance. As Satsuki was about to deliver the final blow a twinkle of light appeared as a red needle and sewing pin appeared. Stopping the blow Ryūko had lost consciousness and was taken to safety by Mako.
"Hmph so you have a weapon similar to hers as well?" Satsuki questions
"I believe that's enough show and tell for one day." Tatsuo smirked
He gently grazed a fingernail along Junketsu as it reverted to its dormant state which shocked Satsuki.
"Who are you?" Satsuki questioned
"My name is Tatsuo Kiryuin, I'm your little brother." Tatsuo answered
Satsuki's eyes widened as she dropped her sword and backed several inches as she observed the teenager before her.
"We'll talk later, also mother isn't going to be happy you wore your wedding dress." Tatsuo smiles before disappearing
Tatsuo was making sure that Ryūko is comfortable while he washed and ironed Senketsu.
"Thank you for stepping in." Senketsu said
"It's no problem." Tatsuo smiled
Tatsuo bit the tip of his finger as droplets of his blood dripped into the fibers of Senketsu. Senketsu felt reinvigorated as he felt a similarity between Tatsuo's blood and Ryūko's.
"Your blood?" Senketsu questioned
Tatsuo put his fingers to his lips as he smiled softly before putting Senketsu on a hanger and began to make something to eat for both himself and Ryūko. Ryūko suddenly awoke grabbing her scissor blade when the weapon was blocked. She gasped as she saw a weapon similar but in the shape of a needle.
"Whoa there." Tatsuo smiles
"Wh-where am I?" Ryūko asked
"You're in my apartment. Here eat this." Tatsuo replies sliding a bowl filled with rice and various meats
"Thank you." Ryūko responded before eating her food as her eyes lit up as she began to devour the food
After her fourth bowl she smiled happily before gazing at Tatsuo's needle and sewing pin blades.
"Where'd you get those?" Ryūko asks
"They were a gift from a colleague of my father's." Tatsuo answers
"Where is he?" Ryūko asks
"He's dead, but that's what I was told since I was able to walk. I don't even know what my mother looks like. I've been on my own for a very long time. During that time I was sent to very prestigious private schools before I took control of myself and transferred to Honnōji Academy." Tatsuo explained
Ryūko looked at Tatsuo seeing a similarity between herself and Tatsuo.
