Cube

Cube is Yucie's steward, a demon who left the Demon World in order to serve humans, especially Gunbard and Yucie. He lives in Yucie's house and serves her and her father.

Appearance
Cube makes his first appearance in the debut episode of the series as Yucie and Gunbard's butler, often using his summoning powers to sate his mistress's desires and wishes. He is a mocha-skinned young man in appearance with pointed ears, plum-colored hair, and blue, pupil-less eyes. He is most commonly seen wearing a navy blue uniform consisting of a long-sleeved shirt with a red emblem on it's front and an odd pants/shoes one-piece. While he appears no taller than Yucie and her friends, it is implied that he is, if not an adult, near to being one.

Cube takes his duties to Yucie and Gunbard seriously, often trying to ease household conflicts by playing middle-man between them, but usually covering the daughter over the father. Just as he tries to remind Yucie that her father only dotes on her because he loves her, he also tries to delicately explain to Gunbard that Yucie is not a child anymore and needs her space. Needless to say, his efforts often fall on deaf ears.

When not tending to his chores around the house or paying respects to Lord Drago, Cube can most usually be found tagging after Yucie to try and keep her out of trouble or to ensure that she isn't overworking herself. He usually acts as a much-needed voice of reason, as well as a gateway to helpful magical items which are supplied to him by a summoned demon merchant, Soraoto, making him a valuable ally.

Personality
Of the five stewards in the series, one might guess that Cube has been a servant for the least amount of time. His heart is in the right place, and he takes his tasks seriously, but there is still a lingering, youthful flightiness to him. He becomes flustered at being given more work than he originally agreed to take on, and, if it will move Yucie's plans forward, is not above deceiving her father or knowingly trespassing.

It is quite apparent that Cube's loyalties lay, for mostly, with Gunbard, whom he goes out of his way to respect and not disappoint under most circumstances. When it comes to Yucie, Cube treats her with an almost brotherly sort of affection with no reservations about voicing his exasperation with her when she does something reckless, complaining if he feels she may get them into trouble, or playfully teasing her, but never forgetting giving courteous label to his master and mistress.

Gaga's accusations that Cube's "carefree attitude" and "sloppy behavior" are contributing factors to his failure as a real steward aren't entirely unfounded as they bar him from fully becoming Yucie's unwavering follower and tireless advocate, mostly because he was labelled as a traitor to the Demons because he was an exile and serving lowly Humans. However, the very fact he DOES linger a few steps behind the role that's expected of him affords him the luxury of approaching most situations with a cool head and thinking them out logically instead of letting emotion be his only guide.

In addition to the other things that set him apart from most demons, Cube seems to have little care for past grudges against him. There had been a point in the past when Cube had been Princess Glenda's steward, but when he was exiled by Glenda's mother, he abandoned his duties in favor of serving Gunbard's household instead, Gaga took over his role. The Queen banished him from the Demon World entirely, and bitter feelings toward him on Glenda's part, due to him not only abandoning the Demon World, he also became reduced himself to be a lowly servant to Humans, particularly Gunbard and Yucie. Despite this, Cube is always quick to greet her with pleasantness in seeming good faith that she'll eventually forget she was angry with him, with not quite good results oftentimes. He seems to have maintained contact and good terms with the Demon King, to the point he was massaging the King, who was apparently unaware he'd even been banished in the first place.

As a demon residing in the Human World, Cube tries to be careful about the ways he draws attention to himself. He does his best to appear friendly and rule-abiding, though can be easily convinced to abuse his access to the Demon World's cache of spells, devices, and potions for the sake of disturbing the peace if an emergency (or Yucie) demands it, or usually to sate his mistress's desires, and shown to have lots of money required to summon things. Despite being the supplier of the means, however, Cube usually tries to quietly distance himself from Yucie's hijinks to avoid becoming directly involved in it. He is also sometimes displaying his cute side.

Appearance
Despite being a Demon, he has no horns, and he has dark skin. He is small, but can use transformation, but in short time.

Background
He was a Demon banished by Glenda's mother many years ago. Gunbard found him and took him on his house, in exchange of being a steward on his home. He became also Yucie's steward too.

Yucie
He is Yucie's steward and servant. He helps her mistress with anything, from simple instructions, covering his mistress to summoning artifacts, using his magic and money.

But he was not always covering for her hijinks, as he also teaches his mistress discipline whenever he can.

Gunbard
Although it is unknown how Cube and Gunbard met, maybe after he adopted Yucie, Gunbard tasked him to serve his daughter, but he serves them wholeheartedly and loyally.

Glenda
She sees him to be a traitor to the Demons, as he was serving lowly Humans such as Gunbard and Yucie. But on his part, being the former steward of the Demon Princess, he is always shown to have polite attitude to her.

Gaga
He develops a friendly rivalry with Gaga, the latter hating him for being an exile.

Demon King
Cube massages the Demon King sometimes and he doesn't even know he's banished. He had quite good relationship with him, despite his wife the cause of his exile.

Odd Facts and Trivia

 * The incantation Cube recites to summon Soraoto's store of items, "Madaraiatza das perifa LIL cahisa" is taken directly from the opening of the Call of the Aethyr LIL as seen in the publication, The Equinox by Aleister Crowley.
 * Despite others' resemblances to previous characters in the Princess Maker series, Cube is the only confirmed character from the games to have made an appearance in Puchi Puri Yuushi.
 * In the manga, Cube has an "adult form" which he claims he can only assume for mere minutes a day. The reason behind this is never explained, though it implies that he is much older than he appears and that he, too, suffers from a curse of some sort - perhaps a punishment that came with his being banished from the Demon World.
