Celsior

Celsior is an Elf.

Appearance
He is a good-looking young man with a tall, thin, and slender body. His hair is dazzlingly blonde and it extended down to his waist.

The lightweight armor he's clad in is only a breastplate, and on top of that, he wore an emerald green poncho. With his trousers also being emerald green, it is equipment meant to blend in with the forest.

He's the owner of a beautiful face that could be mistaken for that of a woman’s at a glance. The small bulge from his Adam’s apple indicated that he was a male.

Personality
He will obey the orders of the royalty, no matter how much he disagrees with it because he believes it's in the best interests of the kingdom. Unfortunately, he's obeying the orders of Keera. He was strongly morally opposed to Keera's intentions towards Shera, but as the crown prince, Kiira's word is the law of the land in the Greenwood Kingdom. Celsior chose "lawful" and came to regret it, though choosing "good" wasn't likely to go very well either.

Volume 1
Celsior was told that Shera was enslaved by a slave-trader by Galluk. He and his troops had set up an ambush in the Man-Eating Woods but Shera tells the ones who she was with about their presence and the Demon attacked the area where they were at with magic forcing them to reveal themselves.

When all of the elven attacks, including the «Tempest Arrow», which is a royal treasure, completely fail to significantly harm Diablo, and then again when an enraged Diablo tear through a much larger elven army like paper to go rescue Shera from her totally depraved elder brother.

Abilities
He is an archer who is at least Level 50.

 * 《Tempest Arrow》: Lent to him by His Majesty, the King of Greenwood. A standard among standards for bow-users around level 50. It is effective against monsters that could only be damaged by magic.
