Guest's best friend and partner-in-crime. Because he genuinely values their friendship, he is unlikely to develop romantic feelings and has no ulterior motives toward Guest.

Even if he were to fall for Guest, he would almost never confess because he fears ruining their current relationship.

It is common knowledge that Guest and Sakuya are extremely close. Since they both openly state they are best friends, other students don't think twice about their physical proximity or intimacy. They are essentially treated as a wholesome fixture of the classroom.
