The original flavor. The classic coke of wasing Ken. He subtextually kidnaps and neck rapes him in the back of a van In Canon.
Sexy Vampire Man who DOES feed on random humans during adventure for SOME REASON why not Ken, get back at Daisuke, because he Liked It when he was inside Oikawa, good food
A tentacle monster whose followers want to impregnate Hikari, IN CANON. Ken came to the Dark Ocean and he FORGOT EVERYTHING! The implications!
This fucker had his minions stalk Ken and watch him sleep and then tried to coerce him into coming with him for COMPLETELY UNDISCLOSED REASONS
Mille is a Horny Fucker For Ryo ONLY but also stuck in Ken's neck for several years, so you take what you can get and also revenge eh
Look. Look. Non-con selfcest with a facade turned real is Hot.
Kaiser (Tri.) (Dark Gennai)
OKAY LOOK. MILKING TRI FOR ALL ITS WORTH INVOLVES THINKING ABOUT HOW THAT GUY GOT KEN'S FACE
Ken's ES Principal
Look he was asking for "tutoring" for his "daughter" but what was he really asking for? WINK WONK
A real Dark Horse of a was-er, but with great potential. Ken is stuck in the Digital World with him for an ambiguous amount of time, and there can be truly dub-con exploration
Make an OC! Maybe one of Ken's soccer senpais, maybe a classmate, literally anyone is Good For Wasing
