I'm not bipolar in any way, shape, or form but my personality I have been told by some people that I remind them of Rentaro Satomi and Arata Kasuga
Rentaro is that type of guy who would literally take a bullet, get stabbed just to protect the people who are most important to him (mainly Enju) . He's always calm, cool and collected and doesn't care if the odds are stacked against him in a fight. He also has a heart for all the Cursed Children in the Tokyo Area.
Arata Kasuga doesn't let anything in the world get to him. He's rarely ever gets Angry, he can be arrogant. When it comes to problem solving he usually does the most irrational thing to do first eliminating any further panic among his friends. He's also one of the funniest pervs in anime. Not to mention he's the Strongest mage and the True Demon Lord Candidate
