Semarel Buren is a 16 year old boy.

He is from the same village as Laerela (https://www.artstation.com/artwork/v1Z5Yx). He was her first friend, although the first time he met her, she was afraid of him.

Semarel is a shy, low self-esteemed person. His friends call him "swallow" because usually he is distracted with his thoughts.

When his village was destroyed by an airship, Semarel had to scape from destruction with Laerela to the sea, where they cried because they lost all their lifes.
