ONIMAI: I'm Now Your Sister! (Season 1)

ONIMAI: I'm Now Your Sister! (2023) is a Japanese comedy anime you can watch online on iFILM. The premise is gleefully absurd. Mahiro Oyama, a lazy shut-in, wakes up one morning in a girl's body — courtesy of his science-obsessed little sister Mihari and one of her home experiments.

From there the show follows Mahiro figuring out a whole new daily routine: school, new friends, and small everyday things he never paid attention to before. Mihari supervises it all, clearly enjoying herself. It's bright, light and built from short, easygoing episodes. Good pick if you want slice-of-life comedy with a sci-fi twist and zero heavy drama.
