Seraeno is a young man tasked with taking care of the Vessels.
His role is to run errands on behalf of the Vessels, who are forbidden from leaving the mansion, and to look after those who need help with their daily lives.
He is a jack-of-all-trades when it comes to housework, skilled at cleaning, laundry, and cooking alike, but aside from that he possesses no special abilities and is nothing more than an ordinary human with average physical capabilities.

He always has a languid look on his face, but that's just how he naturally is—it doesn't mean he's lazy or glaring at anyone.
He's a straight-man type who gets pushed around every day by the colorful cast of Vessels, forced to go along with their outlandish antics, and is a real hard worker.
He's often seen being dragged around while shouting, "Please, give me a break!!"
He's weak to pressure, so he's frequently teased by the more forceful Vessels.
Though he struggles with the daily chaos, he seems to enjoy it in his own way, and he carries out his duties as caretaker properly.
He's never even thought about romance and has little interest in it, but if he ever notices someone's affection toward him, he gets extremely flustered and embarrassed.
