Hikaru is standing on the platform of Tokyo Station. For Tsuna and his other fellows who had risked their lives in order to help her, and for the city of Tokyo where she was born and raised, Hikaru steps into the very origin of her fate.
東京駅のホームに立つヒカル。
身の危険も顧みず自分を助けてくれた綱たちを、そして自分が生まれ育った『東京』という街を助けたい。
その強い思いを胸に秘め、因果の始まりの場所へと、足を踏み出すのだった。
