April arrives, and Mirai is now a high school student. He heads to school on the day of his entrance ceremony, where he sees an angel flying overhead... and is shot by his childhood friend Saki Hanakago's Red Arrow of love. Having fallen for Revel, the angel's trick, Mirai is willing to give his own life to protect Saki. He decides to sacrifice himself to take down another God candidate, but... Meanwhile, masked God candidate Metropoliman makes his move, and the situation enters a new phase.

The battle they just had at Grand Tower cast a shadow on Mirai and the others in many ways. Saki, who wasn't able to participate in the fight, seems to be bothered by something. She then asks Mirai to kill her. Why was the kind and ordinary girl Saki chosen to be a God Candidate? Mirai finds out the truth and then asks Saki to make a certain choice. Meanwhile, high school student Kanade Uryu, who was actually Metropoliman, seems to be plotting his next move as well.
