Sei Array セイ・アレイ

Sei and his bird, Kantaro, are from the Land of Magic. While Sei is initially only after the source of Himeko's magic, which is her bow, he eventually grows to befriend Himeko (in particular, although she does not return it so whole-heartedly) and Daichi once his roots and intentions are found out by the two, becoming their friend (or at least their ally) rather than their enemy.
