[ Pft- ] Uh?? That's the one time you can't punch them! Taiki'll get sad! You can't even beat up anything coming after him without him getting sad!

[ Which he's saying less as a complaint and more as just objective fact. You can't punch a bully in front of Taiki, bro! No, instead- ]

You need to take Taiki away and then hope you meet them later, and then knock their lights out if they start up again. There's nothing wrong with punching bullies!
