The Anime Lad
Kintaro Oe completed all his university coursework and left before graduating. He now travels by bicycle, taking whatever jobs will teach him about life and the world. He is hardworking and unusually capable. His interest in women repeatedly interferes with presenting either quality. Independent study has proceeded without an ethics committee.
Super Eyepatch Fox
Kintaro cycles from place to place as a wandering student. He accepts almost any job and approaches each one as a chance to learn. His foolish appearance hides real intelligence and determination, especially from the women he meets. The six-episode OVA repeats that tension across new workplaces while Kintaro keeps moving.
Gigguku
Kintaro finished the coursework, left the university, grabbed a bicycle, and turned every new job into class. That level of self-directed effort would be inspiring if his behavior around women did not keep detonating his dignity. The fun is in watching someone look completely hopeless while working hard enough to force a second opinion. His wandering-student idea is gloriously earnest beneath the sleaze.
Father's Basement
Kintaro's fixation on women pushes the comedy into conduct that has aged poorly, and that is a real barrier. The structure survives because he is more than a leering fool. He completed his coursework, works hard, and treats each temporary job as education. That concealed ability creates a dependable reversal without excusing the behavior used to hide it.
