Tics are sudden twitches, movements, or sounds that people do repeatedly. People who have tics cannot stop their body from doing these things. For example, a person might keep blinking over and over. Or, a person might make a grunting sound unwillingly. Having tics is a little bit like having hiccups. Rumi Usagiyama (兎うさぎ山やまルミ, Usagiyama Rumi?), also known as Rabbit Hero: Mirko (ラビットヒーロー ミルコ, Rabitto Hīrō Miruko?), is the current No. 5 Pro Hero.
