This is a really great program you have to watch it if you haven't. It's about a person called haru who is obsessed with water anyways every day a day a giant green man called makoto breaks into his house and yanks him out the tub. There is this one teacher who forces the children to clean the pool even though that is like really unsanitary and makes me worry for the 5 year old (Nagisa) this was my only complaint. I spent one whole night thinking that know one would notice if rei drowned since his hair is the Same colour as the pool (blue) this can be a little scary for younger audiences. Rin is very threatening with his sharp teeth that resemble a shark so if you don't like sharks it could give you ptsd if you have been involved in a shark attack (unclear why looks like a shark I think his dad was jaws). There is this one girl gou or kou we just don't know and whenever she is in the frame you may think she is rin and Nagisa is a little bit threatening towards her. My favourite character happens to be the pizza man/ coach since he never forgets to bring his shirt to the school (don't take this the wrong way he is not a creep he is their coach). The water in free is extremely beautiful deep and elegant but not easy on the eyes since it is very shiny and bright and sparkling and spacious. This is a not a joke thanks bye
