https://youtu.be/G-k8_aovPj4 Shellin Propnight Collab with Nijinoon Wednesday in 30 minutes.
Speaking of which, during Nijinoon backstage Rion asked Shellin why he doesn't collab often (outside of official programs), he said he just doesn't have much opportunity to do so and some people think he's rather hard to approach.
So he does acknowledge that he's being rather passive about collabing. He generally won't decline an invitation unless it clashes with his sched or it's Inutama's Ikebo Host Club, but rarely get other people to play with him.
