Author’s Comment
"Lately, there have been a lot of depressing conversations happening in the manga industry. Whenever I go out to eat with my mangaka buddies, they are always talking about how sales numbers are going down, or how they can not get a volume published, or how their manga is being uploaded to illegal manga sites...In the past we always used to talk about fun stuff like "I am getting serialized!" or "Have you read this manga? It is really good!" or "I really want to draw a manga like this..." The world has become a painful place...Well, whatever! Let us eat some snacks!"
