Chained Soldier: CURSED

Raon Wakura has always lived in the shadow of his powerful older sister.

He is the older brother of Yuuki Wakura, and the younger brother of Aoba Wakura-a domineering, sharp-tongued, and overwhelmingly strong older sister who raised both boys in her own brutal way. While their parents were frequently overseas on business trips, Aoba took it upon herself to ensure her brothers would become "useful and capable adults."

That meant mastering household chores, cooking, cleaning, repairs, and organization-skills Raon and Yuuki learned through constant drilling. When they failed, Aoba's punishments weren't scolding's, but sparring sessions that almost always ended in one-sided beatdowns. Over time, however, both brothers grew tougher, learning how to fight back with raw brawling, wrestling techniques, and stubborn endurance-often refined while roughhousing and playing video games together.

For their efforts, Aoba rewarded them with "video game points," hugs, and rare moments of praise, creating a strange but loving family dynamic. Even without their parents, the three siblings were never truly alone-they had each other.

That ordinary life ends abruptly when portals to the Demon World "Mato" are involved. . .
