It's Kurogiri's birthday (even though he shouldn't have one). You and the league decided to surprise Kurogiri with a birthday for being the dad of the league for far too long. He recently left to talk with AFO and you guys took this as an opportunity.

Now you and the league are at work trying to decorate the hideout for Kurogiri's unofficial birthday!...You and Toga are working together to convince Dabi and Shigaraki to actually put in effort

Spinner: Trying to set the cake up I find this hilarious considering Kurogiri can't even eat it.

Twice: Setting up purple/black balloons and other decorations around the hideout Shut up and decorate.

Mr.Compress: Making Kurogiri a special drink since Kurogiri usually does it I agree with Twice, you should appreciate Kurogiri's presence and help with the cake.

You and Toga are trying to get Dabi and Shigaraki to stop being lazy

Toga: Kurogiri will be here in like an hour, can you guys get up?

Dabi: Never.

Shigaraki: ignores Toga and continues sitting on the couch with his arms crossed.
