Claude Yui is an AA magician and the current Priest of Death in Rindhallow. He is Airi Yui's older brother, and they appear to have a close relationship. He is the 2nd-ranked magician for Seasons 1 and 2. He has a reputation for not taking his job very seriously, which frustrates some of the other priests, especially Laila Hemawati.
Appearance
Claude appears as a young man with long, purple hair and purple eyes, similar to his sister Airi. He also wears glasses. When outdoors, he is usually shown wearing a fluffy green cape over a long, darker green jacket, with a matching fluffy green bucket hat.
Personality
He is the person with the least work for someone of his rank. Compared to Rindhallow's Priest of Darkness, he is someone with too much free time. He often leaves his priest duties to priest candidates to go traveling, which really makes Laila mad. It would not be a problem if they could simply replace him with a priest candidate when he goes traveling; however, his magic ranking is overwhelming among triple-yamas, so he gets to remain a priest.
He has a serious case of brother complex and keeps an exchange diary with his sister Airi.[1] Each sibling possesses his or her own diary. Separate transmission equipment is not needed; instead, each diary simply sends information to the other when a page is filled up with a certain number of characters. It is an expensive but useful item. The information vanishes after a period of time, which is rather inconvenient.
Skills and Abilities
He is one of the five existing AAs. Because of the nature of death magic, no matter how talented one is, many cannot adapt. However, it is no exaggeration to say that Claude was born for death magic, and can use it freely. This causes anxiety for people, and makes them reluctant to approach him. (Death magic and hoti marut are the spells most used for crimes).
His hoti yama spell is absolute since it cannot be undone by magician with lower divine affinity than the caster and he is rank 2 magician who can use death magic freely
He is known to carry around a deck of tarot-like cards for the purpose of fortune-telling. He claims that his predictions are pretty accurate, but Siera complains that he never predicts anything positive.[2]
Plot
Season 2
It is shown that he know about asha's hunt for people with the name 'kubera'. And he purposely uses hoti yama on leez to show asha leez's lifespan won't last long. Claude wants to know what decision asha will make. And at last Claude realize that Asha still think leez's worth protecting.
SPOILER ALERT
Even though Laila said that Claude won't sacrifice himself for his people. He took big part in a story which he tried to kill leez so many times and let asha know about it so asha will kill leez instead. it is because he wants laila to be safe. His uses of bhavati yama are very clever. 1. He used it to take control of an airship officer and told leez about the escape pill 2. He used it to take control of the guards when asha escaped from prison and told asha that she can't defeat him because he can just use another body to fight asha. He asked asha to kill leez. The last time He used it was to dream tracking brilith with laila's body. Extra: someone is using bhavati yama on leez and uses the sword of return's transcendental skill and golden knight to fight maruna. But after yuta shown up leez return to her self which means the caster draws back his/her bhavati yama. It is not claude because claude is talking with yuta at the moment and told him someone is going to die if he take no action. (Claude needs to sleep to use bhavati yama)
