OMG me too!
I was there a few days ago and bought all 3 volume and 1 keychain even though I don'tknow shit about reading Japanese..
Omg I'm so jealous! Hahaha
Please give some spoilers
It's not like I don't want to give one, but I haven't open the seal for the comic yet until now, since I don't understand Japanese and was buying it only to support the author anyway..
The next best thing I can offer would be some of the pics and video I took of the pop-up at Animate, if you're interested in it ofc
I'm currently in Japan for this manga's promotion in animate and they have so much merch for it
