I hope jiwoo friends grow stronger too..

Bro i agreee like only he is growing super fast and before it used to show how his friends and him used their powers and strength together and fought and won but now only jiwoo is growing super fast. I want other friends to grow as well so that they have a gang and can fight others.

I agree.

I was kinda hoping they'll be trained and be given their chakra(?) (what do you call their force thingy again?) by Pluton, Kartein or Gestella so they be stronger as well.
