like imagine if
anya: thinks Mob is a secret agent because he acts really boring but hides his psychic powers, and knows he's a good guy because only good guys worry about whether they'll hurt people! Determined to support him with his problems on his mission for world peace. Thinks she's hiding the fact she's psychic from him perfectly. isn't.
mob: Likes this tiny child because she always lets him pet her dog and says what she thinks. knows anya is psychic but doesn't care because it's just one part of her
They hang out in the park after school on occasion. Anya thinks Mob is a dumb codename (but uses it because she can't pronounce Shigeo)
anya: "math is the wooooorst" mob: "yeah. i don't know how my master is so good at accounting" anya: (mind-reading a picture of the spirits and such office) 😮 da spy master has entire filing shelves of secret documents!!
how they met: after school, mob is walking home when he sees the forger family walking their dog. it's so cute. too cute. mob must pet it. but wait- it would be rude to just walk up and pet the dog! mob's percentage starts ticking up. they look so happy talking amongst theirselves without any interruptions! (+1%) they're on a walk so asking to pet the dog would be stopping their walk (+2%) and he couldn't just interrupt them (+3%) but that is such a cute dog- "heyyyy flat hair you look super duper explodey nervous wanna pet my doggy his name's bond"
reigen is torn between "aww glad mob made another friend" and "oh no if mob becomes a babysitter i'm out of a helper for the day". He has absolutely no idea how to interact with a five year old with no respect for anything he says. Anya thinks he's a super duper liar which must mean he's a super duper master spy! dimple posesses anya's stuffed animal Mr. Chimera to try to scare her while she's playing with it. anya beats him up
