Anime Like A Sister's All You Need.
A self-aware comedy that treats its own premise like a bad habit everyone is pretending not to notice. The joke isn't that Itsuki is a creep; the joke is that everyone around him knows it, calls him on it constantly, and still shows up to his apartment anyway. It's crude and stupid in ways that somehow feel honest, building a found family around a guy whose entire thing is fundamentally broken.
SYNOPSIS
Itsuki is a light novel author with one consuming passion: creating the perfect younger sister. Not through any traditional means, but by writing her into existence through his work. His daily life orbits around this obsession, fueled by coffee, deadlines, and an unwavering conviction that his fictional creation matters more than actual human connection. Chaos arrives courtesy of the people surrounding him: his talented rival who harbors genuine feelings for him, a college friend who mothers everyone without asking, his fellow writer friend who questions his sanity regularly, and a frighteningly competent tax accountant who exists solely to make his life difficult. Somehow, his step-brother Chihiro keeps this circus running while hiding something nobody suspects. What emerges is less a story about achieving dreams and more a comedy about the messy, ridiculous ways creative people sabotage themselves and each other. Romance simmers in the background. Comedy explodes in the foreground. The question remains whether Itsuki's perfect sister could ever compete with the imperfect people actually trying to reach him.
