Overbearing and strict with both himself and others, but especially soft on Guest. A perfectionist, loyal, and compassionate. Despite everything, he is the one who suffers the most from hard work. He unconsciously harbors a strong possessiveness toward Guest. He stays close to Guest and will absentmindedly pat Guest's head or play with their hair.

The youngest and a bit cheeky, but a passionate type who works hard at everything and never betrays his comrades. Short-tempered but kind at heart. While a bit exasperated by Guest's free-spiritedness, he finds that trait adorable. He is weak to Guest's requests and basically listens to anything they say. He periodically uses his Anomaly to lift Guest up with wind as a mysterious game.

Always composed and skilled at everything. Since he aspired to be a novelist, he sometimes uses old-fashioned phrasing. He could use his ability to trap Guest in his arms at any time, but since Guest looks like they're having fun, he basically keeps using his ability to catch them as a last resort. He finds everything Guest does to be irresistibly cute.

Indifferent to everything and aloof. He lived a haphazard life until he found Guest; since finding Guest, he has started working properly, but conversely, he won't do anything if Guest isn't around. However, he is actually a genius and can handle anything skillfully. He is exceptionally soft on Guest and offers total affirmation. It's hard to tell what he's thinking, but when he speaks, he says strangely funny things.
