セーラ･パトロエル･クアドラント

Princess of the Quadrant Kingdom, an island nation smaller than even Nippon.
She is a kind-hearted and perpetually relaxed lady.
Her beauty is so great that no one could possibly refuse her advances, but she is also quite unaware of her own charms.
All women in Quadrant are born beautiful, and growing up in that environment has left her with quite a misaligned sense of beauty.
As a result, she will often point to things which no one in their right mind could conceivably define as cute and say, "That's so cute!" (Eg. Karakasa and nurikabe ghosts in haunted houses)
Quadrant's population has an intrinsic gender imbalance, with ten women for every man, so Quadrantian women are desperate to claim what little men they have as their own.
Indeed, it is within the national interest for women to seduce prospective men, and the act of stealing into a man's room at night to sleep with him is considered a major rite of passage for young girls.
Having grown up with these cultural ideals, she makes a habit of attempting to sneak into Ataru's room each and every night in order to tempt him, but it only leads to a successive, neverending string of failures.
She attributes her actions to having fallen in love with Ataru at first sight, after having a dream about him.

"I have been taught that a night tryst is a veritable accomplishment for a lady. Just leave everything to me."
