A story about reincarnating as Yuuji Kazami but wait, I have another brother named Yu Ijin and little sister Dayun other than the MCs big sister Kazuki how is this story gonna go? -Crossover between Grisaia series x mercenary enrollment -MC will be the Big brother of the OCs of mercenary enrollment -Early chapters are for introducing the the character developments of the MC but yeah this is a typical isekai story with some gifts but no overpowered supernatural powers, I want the action purely in human level. NEWBIE AUTHOR HERE just trying out please bear with me. I do not own anything from The Fruit of Grisaia series, Mercenary Enrollment or any anime whatsoever.
