Description

A human boy who reluctantly finds himself under the protection of Nyaruko. He tends to attack aliens by stabbing or throwing forks whenever they make him angry. He appears to attack so fast that currently no alien has been able to dodge yet. At first he dislikes aliens and wants to kick them out, but as the story progresses he starts to become more tolerant toward their actions. He is attracted to Nyaruko (in her human form), but is put off by her aggressive advances at the same time. He has also kissed her a few times, the most prominent being their on-screen kiss during the events of the final OVA, Nyaruko F. According to Nyaruko and Kuuko, Mahiro's appearance is strangely attractive to aliens, which explains why Nyaruko falls in love with him after only looking at his profile, as well as why alien criminals wanted to kidnap him.
