Series by 羽海野チカ

Rei Kiriyama, a 17-year-old professional shogi player, has achieved success in the competitive world of shogi but struggles with isolation and emotional scars from his past. Orphaned after a tragic accident, Rei lives alone in Tokyo, grappling with guilt, loneliness, and the pressures of his career. His life begins to change when he meets the Kawamoto sisters—Akari, Hinata, and Momo—who welcome him into their warm, chaotic home, offering him a sense of family he thought he'd lost. As Rei navigates the challenges of shogi matches, personal growth, and newfound connections, he discovers the strength to heal and find his place in the world.

Living in a rundown apartment and scraping by as art students, Yuta Takemoto, Takumi Mayama, and Shinobu Morita share a chaotic yet vibrant life filled with creativity and dreams. When their professor introduces them to Hagumi "Hagu" Hanamoto, a shy and prodigiously talented young artist, their world is turned upside down. As Hagu forms bonds with the group, each member grapples with their own aspirations, unrequited loves, and the uncertainties of youth.
