-Hmm, I see, is that so~. In that case, Mister will... -...do Marisa a special favor and let her take it easy. (The arrow box says either "sleepwalking" or "night exercise", I can't find a proper translation)
It needs a bit of a change of wording for accuracy. If you'll excuse me: -- (alter to baby-yu-speak and slur as appropriate) 1. Komarisa: "I won't say 'shitty old hag' and stuff anymore! I won't drink water without permission either!" "So please! I'm begging you, please let me take it easy! Please!"
2. Anon: "Oh, I see, I see. Well, than, just this once..." "Mister will help Marisa take it easy."
