Jitsu wa Ore, Saikyou deshita? - Ch. 129 - An Unknown Threat?

[cokelemon]

holy grail ? 7 magical girls? this is reference from anime fate series & yamada-kun and the seven witches or sailor moon ?

thank you for translating

Been a long time since I completed Yamada but I doubt it's referencing that series because Yamada was the sole supporter iirc
