1.what spot makes them BEG for mercy?
kageyama’s feet are definitely his death spot. specifically: the tops of his feet, and all around his toes (under, between, + the pads). the easiest way to break him is to sit on his ankles and just tickle his feet hard and merciless until he’s limp and wheezing
2.are wake up tickles a thing?
PLS give this boy wakeup tickles he deserves them... he gets overwhelmed and snappy if he’s tickled really intensely first thing in the morning, but there’s nothing he loves more than light, feathery, loving tickles so he wakes up giggly and happy and affectionate.
3.do they react differently to different people tickling them?
definitely doesn’t care for it unless it’s someone he really likes. namely: a significant other, or a teammate. he’s deathly ticklish no matter who tickles him, but he really does not enjoy it if it’s someone he doesn’t like, and he’ll try his damnedest to get away from them. if it’s someone he likes, he still can’t control his flailing, but he doesn’t get mad about it or anything. he’ll never admit it, but he’s constantly yearning for physical closeness and intimacy because he’s so fearful and anxious about socializing with people, and being tickled by someone he likes feels like part of that to him.
4. what’s their laugh like?
the DORKIEST. high-pitched, wheezy giggles. if his ler goes hard enough for long enough, it turns into carefree belly laughs that sound like a heavenly chorus of angels. bless this boy
5.are they embarrassed that they’re ticklish
he’s deathly embarrassed about it, to the point that he probably tries to hide it with fearsome glares and forcing his body to stay still when anyone accidentally brushes his sides/feet. unfortunately for him, the second someone surprises him by poking his sides it’s all over.
6.do they seek revenge after being tickled?
nope, he’s usually too #rekt and he’s really not much of a ler. the exception is those stray moments when he gets some unstoppable curiosity about his lee’s ticklish spots and different kind of laughter and decides to go exploring, upon which he becomes a brutal ler without even realizing it
HE DOES AND HE WORRIES ABOUT IT A LOT ACTUALLY because he’s so nervous about hurting someone but his thrashing is so violent and involuntary... he will probably kick his ler in the face at some point and feel awful about it. needs reassurance that it’s okay. the obvious solution here is tying him up, but the added vulnerability ups his level of ticklishness from “bad” to “paralytic”, so be careful.
8.does verbal teasing make it worse?
SO MUCH WORSE. bc he’s so embarrassed about being ticklish. he doesn’t mind it per se, but he does get red in the face and tries to hide his loose happy grin and squirms around more so than he was before. in middle school, the primary culprit of this was iwaizumi, who was a wonderful senpai who picked up on how affection-starved kageyama was and took it upon himself to cheer the first-year up whenever he could via tickling the shit out of him and chuckling along with him about how ticklish he was. in high school, he falls victim most often to suga, whose teasing is vicious.
