Backtagging: Yes. All the backtagging!
Threadhopping: Go right ahead!
Fourthwalling: Ask first please.
Offensive subjects: TBA

Hugging this character: You can but unless he knows you/likes you, don't expect a nice response. He's more open to men hugging him than women.
Kissing this character: Same as above. If you're a woman, unless he likes you, you're going to get shoved/slapped away.
Flirting with this character: Yes please.
Fighting with this character: Minor fighting is okay but if it's going to be an all out brawl, let's discuss it OOCly first.
Injuring this character: Raikov's a stickler for keeping his body as spotless as possible. I'd also like to stay away from permanently damaging him. Temporary injuries are fine though.
Killing this character: No. That ain't my cup of tea.
Using telepathy/mind reading abilities on this character: Ask me first.

Warnings: Raikov is extremely sexual when it comes to men who catch his attention. Most of the time he'll go for a crotchgrab upon first meeting or just straight up try to seduce them - he's basically a sex offender. If that's a bit too in-your-face-sexuality, just let me know and I can tone it down.
