Chapitre 474: Rainbow Ascension

Even though Theo and the others couldn't get enough of their underwater adventure, they still had to leave at some point.

When Matue, their chief diving instructor, noticed that their oxygen tanks were approaching low numbers, he immediately called them to follow him upwards.

Theo, Aurora, and the others were a little bummed that they had to leave their new friends, but they still followed the instructors.

Just like that, they slowly swam upwards as they mustered all their strength to do it. As they did that, they understood why Matue said that they had to be calm and steady when they swam upwards. They could feel it was much easier to swim downwards than upwards. Plus, they had to do it slowly to not decompress too quickly.
