Hinata Sunohara

A young Japanese highschooler and orphan who lives by himself in an apartment building. His parents died in a car accident, which he has long felt guilty about since he had diverted his father's attention while he was driving. Because of his selflessness and kindness, he was summoned to a fantasy world to act as a fighter in the adventuring party which was destined to vanquish a powerful Demon Lord. During his time there, he caught the heart of his fellow party member Mariabelle, who obsessively follows him to Earth after he is returned following the Demon Lord's demise. Although he does care for Mariabelle, her blatantly suggestive flirtations leave him extremely flustered. (Source: Wikipedia)
