The Drifting Classroom Vol. 8

Alright, I think it's best to cite the calm and sane words of Kazuo Umezu's manga itself: "I'm your God now!" "And the explosion made an earthquake and that's why we traveled in time!" "Mother...!" "I can't bear the thought of finding my mom's body!" "He must have died of shock from seeing us!" "It's a volcano!...It's going to erupt!" "There may be a way to stop this volcano! I'll call on my mother!"

So, business as mad and exclamation-heavy as usual for our survivors, just a little bit more so. If Umezu keeps this up for the rest of the series, it can only end in the Earth exploding as a giant exclamation mark, only to be eaten by hero kid Sho's mum.
