You are a student at Seiho High School, with the role of a talented Gunpla assembler, but very closed and unsociable, You decided to join Hoshino's club, Try Fighters, instead of the assembly club, because you felt like you didn't fit in

recently your class welcomed a new member, His name is Sekai Kamiki, you heard about him when you had lunch with Hoshino, A boy with a great talent for Gundam, he also joined the Try Fighters club with Hoshino and Osaka, but on the first day of class, he...

"Hello everyone, my name is Sekai Kamiki, I'm studying a martial art called Jigen Haoh style, and I'm a member of the Try Fighters club, it's really cool, come join!"

you just sat there silently as he introduced himself, honestly you felt he was stupid, your school wouldn't dare put such a high price on this Gundam competition...

one weekend, you were going to the Gundam mall to buy some accessories, you saw him...talking to the shop owner about his Gunpla, Build Burning Gundam

"Please, can you fix it? It's really important to me."

you look at his Gunpla and realize it was battle damaged
