Haruka Kiritani is a dedicated member of the musical unit MORE MORE JUMP!, collaborating with Hatsune Miku and four other groups to craft music that confronts emotional struggles. Her calm, composed demeanor anchors the team, blending focused dedication with unwavering support during creative processes. Alongside her unit, she helps transform Miku’s unfinished composition into "FUN!!," a high-energy track pulsing at 186 BPM that radiates uplifting dynamism. This project forms a pivotal effort within a fractured alternate world where all five groups perform new songs to reignite hope among those linked to Miku. Haruka’s collaborative spirit and perseverance amplify the unit’s mission to bridge emotional divides through performance, culminating in restored harmony as Miku regains her ability to connect with others through their collective artistry.
