Yua Hakakeyama (畠山 結愛) is a supporting character featured in both the anime and manga adaptations. A student at Sorasaki High School, she shares a longstanding friendship with Momo Minamoto, dating back to their first year. Her surname merges the kanji for "field" (畠) and "mountain" (山), while her given name combines "bind" (結) and "love" (愛). A key interaction occurs when she embraces Nagi Hokuto following his recovery from a brainwashing drug administered by the antagonistic Moryo organization, their mutual blush hinting at emerging emotional intimacy. Her documented role centers on these connections, with no expanded arcs or additional relationships provided in the source material.
