|Oya Shizuka's Testimony|
- "Anyway, I feel sorry for poor Renacchi. With the time I spent to become a ranked member, when I did rank I was extremely happy. Therefore, when I think of what happened to Renacchi right after becoming a member of Team 4… Even though the culprit is an AKB member, I wonder if it’s someone who doesn’t understand that feeling."
