Quotes

 * (To Tatsumi Oga) "Sorry 'bout this, Tatsumi Oga. I'm a recluse. Its been a while since I went outside, but I left my room just to see you. I just don't have the courage to talk to people. I've been on the Internet this entire time, after all. But when that wasn't enough anymore I decided to go to school. But I couldn't find you. And everyone else was loud as hell...it pissed me off, so I turned them all to stone...only in Ishiyama, though."
 * (To Yōhei Nasu and Shinobu Takamiya) "You're not making any sense. Why would you go this far just to let Oga escape?"
 * (To Kankurō Akahoshi about his relationship with Oga) "What the hell are you guys to him? You're not so close to him that you can be called a team, right? Since I'm a recluse, you won't win me over with emotions." 
 * (To Tatsumi Oga in regards to the fate of Akahoshi and the others) "Turned to stone, of course. All of them. That last one was a damn pain though. But it was so funny, every last one of them. Kept saying, Oga...Oga...like it was a chant. I wished they would've considered me since I had to keep hearing it."
