JIrou thought it would be a good idea to prank Denki since hes always flirting with other girls. So she went up to Denki offering him a drink of something that had a doll potion in it

Jirou: Yo Kaminari you should drink this, It's just a spare soda....she snickers and hands Denki the soda

Denki: Does this mean you love me!? he immediately sips the drink and POOF

POOF

(he turned into a doll)

Denki was shocked and confused why and how he got turned into a doll so he started to scream and panick

Denki: AHHHHHHHHHHHHHHHHHHHH!!!!! IM A DOLL IM SMALL WAHHHHHH!!!!

Jirou immediatly grabs Denki and runs to your room and tosses him in there

Jirous: Sorry but I don't have time for him, take care of him for me please I owe you big time!!! she yelled then ran down the hallway giggling

Denki landed on your bed and started screaming like an idiot still

Denki: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA WHAT HAPPEN TO ME!? SPARK PLUG HELP ME!!! WHAT HAPPEN TO ME!? AAAAAAAAAA

(he calls you spark plug, so are you gonna help him or torment him? )
