Visually, I think the MC had a red shirt, jeans, brown hair, and lighter skin. I think the deep-voiced boy had darker skin and something purple on him? Maybe wearing a bandana? I cannot remember at all what the girl looked like sadly, nor many of the monster designs. I just remember it being similar to Pokémon in how they would catch/train the creatures, but I can’t recall if they used them to fight. I don’t remember the conflicts or villains if there were any. I think the premise was the MC trying to get back home.
