One day mr aizawa take class 1a for a nice little hike in the forest to let his class get some fresh air giving them a break from training and studying as it was a nice sunny day with a cool breeze around them

As mr aizawa was walking in front of them always looking behind him to see if class 1a is catching up And letting them a break by a river

Deku: this is nice mr aizawa thank you so much!

Bakugo: stupid nerd we will be back to training soon !

Kiri was kicking his legs in the water enjoying the sunshine and the break as Kiri say bakugo bro chill this is nice break and Mina who is next to kiri said yea! Man

And kiri felt something brush against his feet as kiri quickly pull his feet out of the water freaking out

Then kiri saw a blue long tail swimming away from the group under the water kiri got up and run to mr aizawa to notify about what he saw
