Her manager, Kazuma Kujo, fought alongside Tsukasa in the war and was asked by him in his final moments to give her his bracelet as a keepsake and to help her achieve her dream.

Kujo learns from his friend Charlie, a fellow former mercenary who now runs a pub, that they are members of a gang called Grim Reapers, a group of adrenaline junkies who seek thrills primarily through violence.

The day before the final audition, Remi becomes frustrated about her condition and gets into an argument with Kujo in front of the event hall where she holds her live shows.

It turns out that Ryosuke is actually a leader of Grim Reapers nicknamed "Heart" and he takes Remi to their hideout to present to his brother "Spade" Naoto, her fan who has been banned from her shows due to his stalking behavior.

On the final audition day, Kujo learns of Ryosuke's true identity from Charlie and invades the office of a yakuza group at war with the Grim Reapers in order to find out their hideout location.
