Background / History

Morino Kei graduated from the Konoha Ninja Academy alongside Uchiha Kai and Hyuga Rei. The three awaited their assignment together and became Aburame Keiichi's students after passing his bell test through their shared refusal to abandon one another. Kei was specifically tied to a stake and denied food during the test after failing individually, but ultimately accepted Kai and Rei's help. 16 29 31

The Third Hokage later disclosed that Kei descends from Lady Momoka, who fought beside the First Hokage during the Warring States period. This heritage explains Kei's unusually powerful physique and chakra for his age. 31

Team Seven's first major field assignment took them to the Land of Hot Water to eliminate and investigate bandits. Their trip later escalated into an A-rank incident involving Kirigakure Anbu at a hot-spring village. Kei was injured during the operation and hospitalized afterward. 36 53 61
