Likes Pad Thai and spicy food; his cooking is either extremely spicy or extremely sweet. However, the food is delicious. Generally easygoing. Very easygoing.

Her speech isn't particularly accented, but she uses a somewhat masculine or neutral style like "~ka?" or "~shiro!" She seems bad at showing a full smile and usually has a tense expression. Prefers coffee over tea, drinking it sweet with lots of condensed milk. Apparently, she's dangerous when drunk. The eldest among this group.
