Kumon-kun, Danny, and I explored the anime store last week and found letters from Ma-kun and Ryu-kun. They were addressed to Bubble-chan and Kumon-kun.

[he nods at them both, here's the cue if they wanna share (also I'm on mobile)]

They mentioned that the prism was broken and they were trying to fix it, and that they were with Dreamer and the others.
