Ultra Yandere

Ultra Yandere (real name Beyo-Yan) is a cosmic gremlin, she is the bastard daughter of the two abstracts Lust and Murder. She devotes herself to a being she calls her "senpai" (technically it should be "sama") and uses violent methods to deter/remove possible opponents and/or obstacles. Much like her parents she is well-versed in the killing arts and is incredibly obsessive towards whoever she deems her love.

This need for a loved one is quite vital to her, there are theories stating she is actually a (demi)goddess, and instead of basic faith as sustenance (as seen with lower level gods) she uses this motivation. She is often emotionless and empty whenever she does not get her love.

History
Ultra Yandere was conceived when the abstracts of lust and murder would mate. The end result was a daughter which both discarded without a second thought. This little girl would quickly grow within a small cyber-planet. The little girl would be contained in a box by the robotic planets living within the world, using her as a powerful vessel or sorts to keep them alive, as the robots have undergone a dark age of energy, or a time where robotic civilizations are now facing problem when it comes to sustenance in the form of energy sources.

Ultra Yandere would soon grow too powerful for their containment, and escape. By the time of her breakout, all of the robotic world was dedicated to the box (and her) as the energy source, as a result an energy famine would happen and the world would be plunged into chaos.Ultra Yandere was the most powerful biological organism on the planet, and by murdering the robots trying to contain her, the surviving biological organisms would begin to worship her as a goddess.

Soon the robots would die out and the biological creatures would be allowed to thrive once more. By this time Ultra Yandere was now capable of controlling some of her power, although she was still incredibly unstable. She would leave the planet, searching the stars and meeting other worlds.

She'd cover countless lightyears, moving from galaxy to galaxy and finding what she will. Then, she would discover her purpose. She would meet her first god of handsomeness. She would dedicate herself to this god, but like most gods and goddesses of physical beauty, he was a narcissist, loving only himself. Ultra Yandere would kill the many women (and men) that desired the god's love.

But she wouldn't be noticed until she killed the goddess of the clouds, who also sought the god's affection, would her actions begin to get noticed. Ultra Yandere did not not know why she wanted to kill, aside from it feeling right, to her it was nature, to her it was what filled her with both purpose and contentment.

Her "senpai" would not feel the same way about her however, her first heartbreak was monumental. Her emotional stability, if there was any, shattered. It was said she would cry until the planet flooded, the ocean swallowing the mountains. The gods would attempt to stop her, but by the first god's attacks, she would undergo a state of murderous intent and rage.

Her murder spree that day added a flood of ichor alongside the flood of tears and saltwater.

This entire cycle would keep going, she would fall in love with a god, or maybe even an incredibly beautiful mortal, and failure would arise, maybe she would be rejected by another narcissistic god, or her feeble mortal lover died. Either way it was a depressing cycle of the girl. Her reputation would grow, she would called the Beyo-Yan, two words which had various other possible meanings, although the most accepted meaning is "Loving Killer".

Soon this cycle would finally get to her, and in her constant emptiness she would seek a place to stay where her hunger to kill could be sated, perhaps without the crushing defeat of love. She would find herself in Aulken, a planet dedicated to hosting gladitorial events composed of both slaves and willing warriors across the universe.

Soon however she would get news of a new and promising contender. This contender would be the Bomb Gremlin. The two would soon meet in a monumental fight in front of billions, she would attempt to suppress her inner urges to obsess and crush him in combat. But suddenly, when she was about to finish him, he would surprise her by hitting her with a molecular oscillation beam, sending her flying back.

Bomb Gremlin would think he had won, but it would later be revealed that Ultra Yandere was more aroused by his molecularly vibrating attack than hurt, this would disturb him, this would then make Ultra Yandere speed blitz him through a wall, and leave him beaten. Instead of killing him however she would spare him, and name him her "senpai". Old habits die hard.

Bomb Gremlin and Ultra Yandere's relationship would then grow, much to the former's sheer discomfort, but due to her power dwarfing his, he was powerless to stop her. This would give him flashbacks of his time at Loliland, the feeling of powerlessness, of weakness, it would tear him apart inside. Soon one night Bomb Gremlin would leave the planet to finally attempt at fully recovering his power. He would stay inside an incredibly bright and large blue star, but during his attempt at regaining power, he would then be interrupted by Ultra Yandere, who would find him and then attempt bind them together, this would lead to their rematch. This time however Bomb Gremlin was stronger and now they were more evenly matched, in the end Bomb Gremlin would defeat her, and leave her on a planet-sized asteroid.

Ultra Yandere would finally fall into a state of deep depression after this. She had spent so long trying to win the heart of who she loved, only to constantly lose it. She would suppress that and move on, trying to drown it in the blood of the arena, only to come back to it and lose once more. It was a battle she could not win.

When Bomb Gremlin would detonate himself and unleash the Essokinetic Unmaker Bomb to kill Doomraiser, she could easily sense him, his essence, and raced to the source of the blast. While all the gods and other celestial entities within the multiverse they were in would be occupied with what the darkness cast upon it was, she would bring her self-proclaimed fiance to one of the moons of the planet Zeuscian, nursing him back to health. Together with him they would "reignite" the Shining Realm and destroy the dark shadow, restoring the Glass City of the Old Ones and allowing the multiverse to shine once more.
