Alef is an alchemist who makes golems out of woods.

An aesthetic who covets beauty. Though it's not quite easy for other people to understand, he has his own sets of "philosophies" on appreciation of beauty. Not only does he appreciate the outer beauty but he also recognizes the inner beauty that's "reflected on" one's looks. He has his own "Lady Radar" and believes one that is ugly on the inside cannot make the radar ring, however beautiful on the outside. When he finds "the real beauty," he willingly becomes a loyal servant of it.

His full name he used back at home was Alefiod. He was the smart one in the prestigious alchemist family, but he always made some trouble with his laziness and fondness for women. His talents had been wasted on creating a gem as a gift for a neighborhood sweetheart, or creating a golem to do all his chores, and such. 

When a war broke out with a neighboring country, he created the ultimate golem out of birch woods at the request of the royal family and successfully protected the country. Thinking golem's powers as an opportunity, the royals tried to start another war. He persistently refused to use his golem for war and was eventually exiled eternally. After leaving his country, he vowed to start a new life and named himself Alef.
