Luke

"'A representative of the Celestial Realm. Has been given the nickname Chihuahua by Lucifer and is often teased.'"

Luke is one of the two angels sent from the Celestial Realm to take part in the exchange program. He and Simeon are to stay in the Devildom for one whole year. He's introduced in Lesson 2-13 along with Simeon.

Appearance
Luke is an angel of short stature with light blond hair, a fair complexion, and blue with yellow gradient eyes. His physical appearance is that of a ten year old but he is at least over one thousand years old.

Personality
Luke is very boisterous and opinionated, especially when it comes to things he dislikes. Due to his small physique and reactive outbursts, he is likened to a Chihuahua by the brothers, Diavolo, and even MC (if the player has chosen so), much to his dismay.

He's quite prejudiced against demons and warned MC to never trust them. Although Luke's narrow-minded, Simeon has stated that he's honest, genuine, and has a strict set of values. Luke is overall a very caring person who has a big heart and cherishes his friends, but he acts tough on the outside and dislikes it when people depict him that way.

Likes

 * In the chat Bandage, Simeon mentions that Luke likes to buy cute bandages and has quite a collection.

Dislikes

 * He's a rather picky eater, for along with disliking "weird" demon cuisine, he dislikes tomatoes (including ketchup) and certain types of cheeses.

Background
Luke used to admire Lucifer even more than Michael when the brothers were still angels. He is likely the youngest character, according to Issue 3 of the RAD Newspaper.

He was unaware of Lilith's existence, for he knew Lucifer to have only six brothers.

Main Story
Luke is one of the three exchange students who reside in Purgatory Hall along with Simeon and Solomon. Despite his often vocal dislike of demons, Luke is frequently in the company of Barbatos, who has been teaching him how to make sweets and desserts. He has been learning how to bake cakes and pastries for about 300 years. This is because Michael loves all kinds of sweet things and Luke wants to present him with a cake.
