Ichigo and Ringo Kobayashi/Kaguya Kobayashi

Kaguya Kobayashi (神夜・小林, Night of the Gods on the Small Grove)

Appearance
Kaguya bears the appearance of a young lady in her mid-late teens, with a slender figure, sizeable bust, and light blue eyes. Kaguya's hair is a light blue, and goes down to her waist in length. It is kept free, and is rather wavy. Her fringe is kept just above her eyes, and she has three sets of bangs; first going down to her upper-jaw, second, upper-neck, third, chest-length

Her attire is mainly yellow in colour, with blue and white covering some parts of her dress. She uses a yellow moon hair clip with a flower petal connected to the curve ends of the moon, white flowers and petal can be seen next to the moon hair clip. While wearing a deep blue uniform, she uses a simple, yellow hair clip. She wears a silver and gold Valkyrie-like suit of armour with a shield on her left arm; appearing majestic, like a goddess.

Equipment
Kojōhaku (湖上白, White on the Lake): Kojōhaku is one of the Divine Tools; unlike the others, it is modeled after a bullet train. The weapon is composed of four separate parts; Sword, Grip, Ax, Gun; that, when not in use, disappear; only for Kaguya to summon them back with a snap of her fingers. Essentially, it is a weapon which can take multiple forms; it has the ability to change into different weapons with a little bit of parts-shuffling. The weapon fully displays various variations in which the weapons are attached in fancy and tricky manners that differ from the norm.

Black Arts
Black Arts (黒い魔法, Kuroi Mahō): Black Arts, also known as Black Magic (黒魔法, Kuro Mahō) are a forbidden type of Lost Magic which stems from Black Mages; it is supposedly nothing but pure evil, and the Black Arts has been known to cause the loss of people's souls if they have delved too deep into it. Slowly suppressed and conquered by the influence of Black Magic, these unfortunate souls become nothing but demons bent on destruction. Those who follow the path of a Black Mage will usually gain untold power at the expense of something of their former selves. Though Black Magic is mostly used by villains and is believed to be pure evil, it is not entirely malevolent; however, different characters have different views on the Black Arts; Gary regards it as nothing but "hate and rage," while Vita insists that light and darkness are interdependent and cannot exist without one another. Receiving a letter of approval from the Magic Council, Kaguya was able to study and learn the Black Arts.

If one can accept the Black Arts into themselves without allowing the darkness to consume them, they may wield its powers without succumbing to its influences; much like Kaguya did; much like Aura Magic, Black Magic can either be used to protect or destroy—it is neither good nor evil; it all depends on the user. Though it is not necessarily "evil" magic per se, dark arts focus toward destruction, harming, cursing and otherwise complicating the lives of other people while advancing the user's own state, embracing magical techniques and practices that would traditionally be viewed as taboo and are generally willing to go farther than most would even consider if it serves their ends. Black Arts are aligned with fear, hatred, aggression, and malice toward all living things.

The Black Arts create and feed off of primal emotions of the caster such as revenge, hate, greed, and fear. In the process, it makes those it affects experience and exhibit these feelings while constantly making those feelings stronger, eventually leading to the affected becoming a demon. The Black Arts can also change the physical appearance of those it affects, up to such extremes as a normal person becoming a demon; or them changing to look as if they were a completely different person. If one relies too heavily on the powers the Black Arts bestow upon them, it will swallow their soul in a matter of time.

Shadow Flare
'Shadow Flare (シャドウフレア, Shadou Furea):
 * Black Lightning: Black Lightning is a powerful Shadow Flare Spell that is a purely offensive, energy-based attack that channeled black magic down Kaguya's limbs, hurling arcing bolts of black electricity from her fingertips or palms; it can be executed with either one or two hands. Powerful discharges can branch out into dozens of smaller forks; thus, she can target several foes at once. She can render a target unconscious with only a short burst, and a single, powerful blast is sufficient to kill a person instantly, allowing her to electrocute her opponents to death on contact, not only instantly killing her target, also physically hurling them backwards. It is powerful enough to render anyone caught in it into charred husks if used to its full potency.

Reverse Soul Magic
Reverse Soul Magic (反魂の魔法, "Hangon no Mahō"): Reverse Soul Magic is a deadly subsection of the Black Arts; more specifically, that of Living Magic. Whereas Living Magic is a type of Magic that allows the user to bring life to their creations, Reverse Soul Magic is a Magic which affects the user's soul. Casting the magic, the user gathers their magical power within their soul and compresses it; this causes a unique effect where the user's other attributes—including their life energy, magical energy, strength, intelligence and knowledge, agility, and finally, their talent in magic, is split into two even halves. Then, the user's body undergoes a process similar to asexual reproduction; however, instead of the user producing two more of themselves, the user indeed does split into two halves. The skills of the user are split amongst the two halves, as well as their personality traits; additionally, the two beings produced are struck with a bad case of amnesia, not remembering anything about their "original self".

However, in most cases, the personality of the original being is heavily diluted within the duo produced; becoming almost one-dimensional. This is because if a person that the original being once knew attempted to talk to them more than just basic greetings or instructions, they would scream in pain and collapse, as memories slowly begin to surface—if the memories fully emerge, one of the two beings will fade out of existence. Due to the lack of a soul, the two beings cannot truly feel emotions; but in most cases, they often pretend that they can, pretending to be "a real human". Through interacting with others, the two beings are able to "remember" what it was like to have emotions, thus allowing them to respond correctly to specific situations. Although the two beings are born as empty shells, they are capable of developing identity of their own over time.

The body of the two beings may be warped to a degree from its original form, depending on the strength of the user's Reverse Soul Magic. Additionally, the shells can be implanted with the soul of another, becoming a vessel for that soul; magic that the two beings possess is more often than not a split between the powers of the original magic. In most cases, Reverse Soul Magic is irreversible; but if both halves of the original being manage to obtain the Merging Magic "Junction", then the original being will be reborn for short periods of time. In a sense, the original being is never truly fully alive again, and can only exist for mere minutes at a time. People have noted that Reverse Soul Magic is eerily similar to how The Exalted One had split itself into Origin and Varian; indeed, the creator of the magic did study up on the mythos of the world in order to create this magic.
