Love Hina

Keitaro and his childhood sweetheart made a promise: they would both get into the prestigious Toudai University and meet there, before she moved out of his life. About ten years later, Keitaro has become an artist and a daydreamer, having placed 27th from the bottom on the national practice exam. When his grandmother leaves the all-girls dormitory, he becomes the resident manager and soon runs into two Todai applicants who might have been that sweetheart, since he has forgotten her name. Then there are the other tenants, like young Shinobu, who was in despair until Keitaro helped her, Motoko the swordmaster who sees men as evil distractions, Su Kaolo the genius child inventor, and the sneaky Kitsune.
