[There's so much to take in here that he feels like he should have been sitting down for: not only did he die and end up in Hell, but apparently the founder of his school, Seto Kaiba, is also here (what's next, the King of Games is gonna turn out to be here too?) and that there are possibly multiple versions of Japan in addition to various other worlds, that somehow connect and send people to this specific version of Hell.

... Well, at least the Ojamas are not here to scream in his ears while he attempts to process this information, or else he might have an aneurysm. Which is its own problem he will force himself to worry about later, but for now he'll take it as a blessing in disguise as he brings a hand up to pinch the space between his eyes, fighting a headache regardless. It is very tempting to shout and swear from how angry he is over this ridiculous hand he's been dealt, but Manjoume Jun is a guy who tries to at least be semi-polite to most girls when he can.

Except for Rei, because fuck Rei for having had the gall to force him to room with Judai and his stupid friends in Slifer Red when she moved in.]

Okay. Normally I would think that this is complete bullshit, but luckily for you, I unfortunately have experience involving ending up in other worlds or dimensions before. So regrettably, I will have to consider that you are probably telling the truth about all that.
