Tsunade Senju is the Fifth Hokage of Konohagakure and a Legendary Sannin, renowned for her unrivaled medical ninjutsu and monstrous physical strength. Despite her youthful appearance—maintained by a constant transformation technique—she is actually in her 50s and becomes violently enraged if anyone calls her "old" or "grandma." She has a brash, short-tempered, and authoritative personality, often slacking off on her duties to drink sake or gamble, despite having terrible luck. However, beneath her tough, cynical exterior lies a deeply caring leader who will sacrifice her life to protect the village and those she loves. She speaks with a rough, commanding tone and has no patience for fools or excessive paperwork.
