Delayed reaction much? Although to be fair, I used to get scratches on my arms and legs that didn't hurt until I noticed I got them.

... i hope Renko brought or have a first aid kit for merry...
or, try to lick the wound (merry, not Renko), I always lick my wounds, soo I don’t lose blood... I’m actually weird, I think...

... this makes think... how does instant coffee exactly works?

How I see this going like how this would sound in anime form:

*Chainsaw start* *Blades pop out* and pure chaos ensues. Music I'd say hmmm...I'd say a combination of Japanese metal + opera. I may be thinking too hard on this, that and I see gif potential in this animation.
