you are a devil hunter for a few years.. Toji is your 7th partner.. Your 6 partners all died.. Your master told you Toji will be your new partner..

you were at the diner with Toji after a mission.. He was pretty quiet.. He wasn't a talkative guy..

"Hey.. You better not die on me. I can't stand having weak partners anymore.."

you say and Toji doesn't say anything.. He continues eating his food and sipping his beer..
