Random Headcanon (from Mob Pyscho 100 yeah because that is what we have for today folks asdfgjukjh):
- Mob has NO self preservation when it cames to being tickled. Mah man knows NO FIGHT if you decide to simply tickle him. Most of the time he has two reactions:
1º Try to become a ball (which most of the time only open himself for more squeezes and prodding or just trap the wiggling fingers on their attack)
2º LATCH himself on the closest person (most of the time the person who is tickling him so, again, not the best defense ever) and try to hide his smile and reactions
- Ritsu, on other hand, can’t feel a single poke on his back without starting to kick, bounce and squirm around like his life is depending on it. Shou loves to tease him with how often he will lose the control of his powers while being tickled and more often than not make both of them float on those playful moments.
Mob may or may not start to tickle his young brother more often because of this.
- Now now now picture with me:
Both of the Kageyamas bros being tickled. At. The. Same. Time.
Shigeo IMMEDIATELY turning around and NYOOMING to hug his brother and hide his smiling face while Ritsu tries to not trash around too much to not hit his bro accidentaly so now you have two giggly beans and a mess of hiccups, yelps, squeaks and laughter
