Nakanoke no Itsutsugo (中野家の五つ子)

Nakanoke no Itsutsugo (中野家の五つ子) is a Japanese group and character unit from The Quintessential Quintuplets, built around the Nakano quintuplets and tied to the voice actresses who portray the five sisters, including Kana Hanazawa. It functions as a cast-based unit in the anime and anison space rather than as a conventional stand-alone pop act, and that connection gives its music a character-song identity, with performances framed within the story world while also released as pop-forward anime music. For Go-Toubun no Hanayome, Nakanoke no Itsutsugo performed the openings "Gotoubun no Kimochi (五等分の気持ち)", "Gotoubun no Katachi (五等分のカタチ)", and "Gotoubun no Kiseki (五等分の軌跡)", and the endings "Gobun no Ichi (ごぶんのいち)", "Hatsukoi (はつこい)", "Go-toubun no Kimochi (五等分の気持ち)", and "5-toubun no Hanayome: Arigato no Hana (五等分の花嫁～ありがとうの花～)". Its presentation remains closely tied to the Nakano sisters through soundtrack releases, character songs, and other anime-related music projects in seiyuu-driven anison releases.
