"Omabien" is a voice drama that came with Young Jump Issues No.12 & 13. Featuring Tsukiyama Shuu, it is voice-acted by the TG anime cast. The script was written by Ishida-sensei. I’ve translated the first 2 stories here. In the first story, Tsukiyama tells the gang a scary story from his childhood. In the second one, he visits Helter Skelter.
