His personality is similar to that of Domon. Like him, Sekai uses a close combat specialized Gunpla, utilizing his martial arts skills. It seems that Sekai doesn't know much about social activities. He is a very straightforward person which is noticed by many people who approach him. This aspect of his personality is both a asset and a weakness when it comes to Gunpla battle which is shown through his battles.
