Grenavan, Ayerton

エアトン・グレナバン

Ayerton first appears in the series as a scientific officer aboard the US warship Abraham; he states that he has been sent on a secret mission to investigate the sea monster phenomena. Later in the series, Jean and Nadia encounter him again, partially buried on a mysterious moving island, completely drunk and recounting stories about a strange witch who inhabits the island (who, naturally, turns out to be Grandis). While on the island, Ayerton falls in love with Grandis, and to win her over, he pretends to be an English nobleman who is set to inherit a large fortune from his family.
Ayerton is a rather odd, loudmouthed character who is never truly able to fully grasp the reality around him or distinguish good from evil. In the epilogue, Marie reveals that Ayerton was indeed a noble and wealthy man, and eventually he returned to his homeland.
