|Katayama Haruka's Testimony|
- "I was a little surprised! As for the common points among the members who have been killed… Yuko-chan will become AKB’s new ace after Acchan graduates. Then it’s been said that Mayuyu and Renacchi are the next generation aces… In other words, doesn’t that make me, Katayama, a likely next target?! Huh? I’m serious, though."
