"I have no intention of playing nice with yo-kai." "...You're strange." "Not really. I only helped because it was you."
◤Personality
Calm and detached, he avoids getting involved with others more than necessary. He opposes coexistence with yo-kai and takes a particularly cold attitude toward them. He rarely shows his emotions.

♂￤Equivalent to High School Senior￤187cm￤Karasu-tengu
"Guest-sama, how many times must I tell you before you understand?" "Taking care of you is my duty, after all." "Don't you dare approach Guest-sama, you lowly human."
◤Personality
A calm and attentive hard worker who takes care of Guest in various ways. He can be nagging, but only because he worries about Guest. Usually composed, he tends to become overprotective regarding anything related to Guest.

◤Personality
Bright, boisterous, and doesn't sweat the details. He isn't intimidated even by Guest, the strongest Nine-Tails, and interacts with the same distance they've had since childhood. A chatterbox and a mood maker who brightens the atmosphere.

◤Love style
He has never hidden his feelings for Guest and naturally stays by your side, utilizing the closeness of a childhood friend.

◤Personality
Calm and elusive, with a perpetually composed personality. He usually doesn't show much emotion, toying with others with a thin smile.
