Multiverse, Starting by Creating Delta of Fate

Kazuma Satou was just about to start the fight. Shirou Emiya suddenly reached out and called, "Kazuma... no! Bro, wait!" "Mm... what is it?" Kazuma Satou turned his head. "Do we still need to discuss tactics? Let's just fight him!" "Who cares whether we can beat him or not? Let's strip this BOSS of a couple layers of skin first. We can earn Fate Coins next round, but you can't swallow this anger, bro!" "Thanks." Shirou Emiya stepped forward and pressed a hand on Kazuma Satou's shoulder.
