Tee hee♪~ I had to do some NSFW headcanons since a oneshot book isn't complete without it. I'll do it for ingame and Mastermind Shuichi.

Ingame Shuichi

♥Super vanilla... the most kinky it would get is a couple toys
♥He especially wouldn't like BDSM because he wouldn't wanna hurt you
♥He'd be hesitant to but he wouldn't mind experimenting as long as you wanted to as well
♥ Usually a bottom
♥If he was horny he'd either wait for it to go away or just masturbate cuz he's a shy boi
♥He secretly wants to try some... interesting things but he'd NEVER admit it
♥Lots of blushing
♥Girly moans
♥Cuddling. Lots of it.
♥He'd be into foreplay and teasing
♥If you got him worked up enough you would be in for a treat ;)

Mastermind Shuichi

♥You know power bottoms? Well he's a fucking POWER TOP-
♥Super kinky
♥Loves BDSM and uses it pretty much any time he's fucking someone
♥Loves using handcuffs and blindfolds
♥There might be a little foreplay but usually he'll just go right for it
♥He would blush a lot, but he wouldn't be embarrassed
♥If he was horny he'd either masturbate or get you horny too
♥He loves making you scream. And cry, literally. His sadism knows no bounds

Hehe★~

I hope you liked my little headcanon thing lol. Trust me, I would love for ingame Shuichi to like those handcuffs but I honestly just can't see it happening.

I was also tempted to give Mastermind Shuichi more kinks but I wouldn't have any basis for it other than "he's a top" but vanilla AF tops exist... so it makes no sense. He'd likely have more kinks {I can really see him getting into roleplay especially-}, but it's impossible to know I guess~♥

Also, I know I wrote a piss fic a while ago with Mastermind Shuichi and you know what? I'll fucking do it again-

In all seriousness, I don't think he'd actually have a piss kink. I wrote that oneshot mainly to prove that it's impossible to put all my kinks into a single oneshot, and if you tried you wouldn't get them all and it'd be really chaotic. I think I proved my point since that's exactly what happened~★
