## Cover Conversation

**Akechi Touma:** Is it finally my turn to take the stage? Very well then, with all due respect, I will try to introduce myself as briefly as possible...Although, I am sure you all have already heard of me, correct? After all, my introductory chapter was in volume 20...However, for those of you who are joining us now...

**Saiki Kusuo:** (Cutting him off) As briefly as possible please.

## Alternative Cover Conversation

**Touma:** My apologies for earlier. Now allow me to provide a simple introduction...My family name is Akechi. The kanji for the “Ake” in “Akechi” is the same as the first Kanji in the word for abundant....Although, I am sure those of you who are fans of manga...

**Kusuo:** (Cutting him off again) Please, keep it simple.

## Character Comment

**Touma:** So this is the first page of Saiki Kusuo no Psi-nan volume 21... I suppose you could call this the title page. The fact that you're reading this must mean that you have in your hands a copy of this book, correct? Thank you very much for your support. Then again, just because you have a copy of the book on hand, doesn't necessarily mean that you purchased it however, statistically speaking I believe those of you who have purchased the book outnumber those who have not. My reasoning is that those reading this at a bookstore or a manga cafe wouldn't want to waste their time reading the words of someone like me who only appears in one panel of volume 21. Yes, I do believe that the only ones who would take the time to read this book cover to cover would be the ones who spent money on it... Yes? What is that you say? "Hey hold on"? "Aren't you forgetting those who borrowed the book from someone, or rented it out"? "Someone do something about this third rate detective"?... Is that what you're thinking? I see... Certainly, it is highly probable.. You've got me there but truthfully that doesn't affect my argument. The point I was trying to make is...Regardless of whether or not they bought the book, the only ones who would read every inch of this book would have to be a very devoted fan. It doesn't matter if the person reading this in a bookstore or at a manga cafe. I simply want to take this opportunity to express a special thanks to those of you who take the time to read these long and unnecessary text segments. Now then, it's about time we get to the main story... Oh, but those of you reading this at a bookstore should hurry up and either buy the book or put it back on the shelf. Now, let us proceed.
