Main Characters
Hiroya Tachibana
- "Don't look like that. I'll figure something out."
A brusque Boxer with a slight attitude, who often tends to be harsh with Kazuha. Though he can sometimes come off as aloof, he is actually a caring person who puts his life on the line for Kazuha in the game world. In real life, he is her childhood friend. Although they played together for years as children, after graduating from junior high, they eventually grew apart. He has been acting distant around her lately for some reason. He is also a good friend of Kazuha’s brother, Shiki, who was the one who invited Hiroya to play Arcadia in the first place. He helps Kazuha find her brother, while at the same time protecting her after she becomes the “Almighty.”

Rei Aijou
- "Like I said, she's none of my concern."
A solitary Dracon Fencer who’s not too fond of lies or jokes in general. He is very straightforward with his opinions, and comes off as rude to the people around him. He is aware of his obvious skill as a swordsman and looks down on Kazuha for not having any power, despite her position as the “Almighty,” and dismisses her as useless. In real life, he’s a popular idol who is fed up with the illusion of fame and being forced to act friendly, so blows off steam by being his true self in the game world.

In order to make Kazuha his, he is very persistent in his approach to her without any regard to those around them. In real life, he attends a prestigious medical school to carry out his father’s plans for him to become a doctor. His focus is purely academic, and as he’s not very sociable, he’s often called “invisible” by his peers. Annoyed by those who don’t acknowledge or respect him, he is frustrated with how different things are in real life versus his life in Arcadia.
Riku Yuuki
- "This is just one of those times when we gotta help each other out. Right?"
A young, mischievously charming Hellion. In Arcadia, she wields her charm to get equipment and money from all sorts of people. After learning that Kazuha is the “Almighty,” she sticks by Kazuha’s side in attempt to use her to her advantage. In real life, she is actually a boy in junior high who is chronically hospitalized.

Originally, he was a NPC who guided people around town and provided players with quests. Upon finding out about his true self through meeting Kazuha, he begins to explore his pure and gentle, but somewhat deviant side. The fact he actually doesn’t exist starts to frustrate him, and his vulnerability begins to rear its head as a result.
