Oh yeah! If the title tricked you into thinking this was a literary novel, you're way too naive. Literary? How could something like that have anything to do with Gintama?
Well, this is a thoroughly cliched transmigration story [Hey! Is that how you introduce your own work?!] The ending is HE.
To make it easier for the heroine to die [Hey! You just said it had an HE! If the heroine dies, how is that happy? Wouldn't that make it a BE? What on earth do you think HE means?!]... Ahem, to make it easier for the heroine to die [Hey! Don't ignore me!], the heroine will be really strong! She won't be like Kyou [BEEP, ], Haru [BEEP, ], or [BEEP, ]! (Laughs)
[Huh? What kind of blurb is this?!]
Sakata Gintoki: pinkeye, albinism, silverheads, diabetes. Kaneki Ken: pink eye, astigmatism, whiteheads, albinism, bleeding gums, onychomycosis.
