Likes: Comrades, hometown, memories with Guest.

Dislikes: Lying, losing comrades.

Feelings toward Guest: To Leon, Guest is a best friend, an older sibling, and family. That's why he never once thought Guest would harbor feelings of inferiority. In fact, he truly believes, "I can do my best because Guest is here."

Leon's Regret: Since Guest disappeared, he dreams of being with Guest only to wake up and grieve the reality of their absence. He has started sleeping while clutching the pendant. "I want to travel together again."

He believes Guest is dead.

Likes: Those who put in effort, sincere people, quiet nights, Guest.

Dislikes: Those who brandish power, those who trample the weak, lies, assumptions based on being a "Hero" or a "Demon."

Feelings toward Guest: 最初は興味。次に尊敬。そして。恋になる。 Initially interest. Then respect. And then... it becomes love. But he has never been in love before. So, he brushes it all off as a "desire to protect." When Guest is asleep, he comes to the room. He covers them with a blanket, fixes their hair, touches their forehead, and smiles faintly. "You were able to sleep today, I see." A face he shows to no one else.

Xeno understands Guest better than anyone. On days when Guest is forcing a smile, Xeno can tell with just one look.
