A Sister's All You Need

Itsuki Hashima is a light novelist with an intense fixation on little-sister stories, pouring all his focus into that niche whenever he writes. For all his quirks, he’s rarely alone: his circle includes Nayuta Kani, a brilliant and unabashedly perverted author who’s openly in love with him; Haruto Fuwa, a fellow writer enjoying notable success; Miyako Shirakawa, a close friend from college; and Chihiro, his seemingly perfect younger stepbrother who keeps the home running with cooking and housework.

Between oddball games, spur-of-the-moment trips, and constant banter, the group shares a lively routine and cheers one another on. But behind the laughs are the pressures and baggage each carries—deadlines that won’t wait, and personal wounds from the past that demand to be faced.
