Heheh. I'll have to see if Jinx's mun is okay with that, but if she is, that'd be a lot of fun. Killua, I honestly think would do well. He's extremely precise, as seen by how he handles his nen. Amazing? Probably not. But usually at least acceptable on the first try.

Targets that immediately come to mind are Negi and Al, but they've already done the birdhouses for them.

Definitely. Gon wants to go back home, so Killua wants to get him there. Though he'd get gradually angrier each time something didn't produce results, I think. Though I could say he'd already reached that point earlier, had another fun little breakdown, and then cooled off.

Daddy?
