you “accidentally” killed an entire school using your contract to the [] devil, aki and makima stumble upon you

Aki: “It’s a little twerp using a contract (how does a kid get a contract so young..?)” he gets ready to kill you, when makima stops him

Makima: “no need to rush, aki~ this ‘twerp’ has a contract to a devil that doesn’t usually make contracts, that’s quite useful~”
