Summary
Kusuo's classmates were enthusiastically setting up their rock displays when Reita suddenly comes in and begs Kusuo to join his band, Eternal Diamond Veronica. Kusuo refuses, but Reita brought up the disaster that happened during the Okinawa School Trip and mentioned all the trouble it caused him, which angered Kusuo as the latter saw it as Reita threatening him. However, he admits that what Reita was saying was true, and he decides to help them as he hates being in someone's debt. He comes to teach the band members and was introduced by Reita as Sai. He then uses Telepathic Broadcast to create an illusion that the music he created was like that of a pro. He uses this power again to make the band members think that the music they create sounded fantastic, causing them to think that they were now pros and required no practice. Kusuo then leaves the room, with Reita silently praising his skills as a psychic. Unknown to the band members, they were still as lousy as they started out.
