Kiriko Zubreska

Kiriko Zubreska (キリコ・ズブレスカ) is a young boy from Ortus who meets Ai and Julie on their journey. He's apprenticing at the office. He's one of Princess Ulla's retainers, and serves as both her friend and teacher. He seems to know Ulla's secret, but keeps that knowledge hidden from her notice.

Appearance
Kiriko has short blue hair with his bangs being split in the middle. He has orange-brownish eyes. He is usually seen wearing a white uniform with a greenish coat-like poncho over it. Both articles of clothing have a gold lining.

Ulla
Kiriko has been Ulla's mentor ever since she was young. The two have become good friends since then. Kiriko is in love with Ulla and think she's a beautiful and kind person. He didn't tell Ulla the truth about her being alive because he didn't want to hurt her, but after hearing the truth from Ai, Ulla still likes Kiriko and doesn't want to be in a world without him. The two are seen sitting close together, reading a letter from Ai about their travels. Whether or not their feelings about each other have been revealed is unknown, but the two are still as close as ever.
