Kris's name is on the save screen by default, but they don't have an actual SAVE file. There's no location or playtime associated with them.
The name just shows up on your save by default, even if it doesn't actually make sense (pic related; Kris definitely doesn't have three save files, those are our save slots that are being managed by Gaster). It's just an indicator that we're overwriting their will.
