Backstory: She was born as an pure-blooded Souleater. She hasn´t a life before and never she wasn´t an human , but she is the only Souleater who can speak the speech of the humans perfectly like her and who also understand the humans . She is verry wise and wants to find someting out about the derivation of the Souleater. Why the Souleater are here? What purpose the Souleater have? Arsimina has a lot of question in her mind . She is studying also the attack of her enemies . Arsimina wants to learn someting about the personality from the person. She likes to read a lot of books, Arsimina loves the light. But Souleater don´t even like the light they love the darkness , because the soulater are connected to the heartless. She is always writing someting down, if she finds someting about the world out or someting about the Souleater. But Arsimina suddenly has an strange feeling and she hears an voice in her mind that say someting to her. The voice said : Arsimina is there someting you that you are missing? Arsimina confusing said :I don´t know . Suddenly a tear is rolling her cheek down. Huh ?? why am I crying? I have no reason to cry, I mean I know the Souleater can feel emotions but... the reason why am I crying. Arsimina thought about it in her mind. The voice in der her mind said : My dear you are crying because someting important is missing in you. It is your soul that you never had your are missing it. But you can´t remember about it. This is the reason why the Souleater are trying to steeling souls from humans . They want all their old ego back . The Souleater are also creatures of the Darkness they want to use the souls for the Darkness. But you my dear you love the light right? Y-yes I love the light. But how do you know? Arisimina asked confused the mysterious voice The voice ignored her question . And the voice told her someting: You are different like the other Souleater you never hunted humans for a soul. But I sense deep in your subconsciousness that you would like to have a soul and your wish is it to study the world and share your knowledge with other right? Arsimina was quite and shocked that the voice knew everything about her. She remembered now about her old time, that deep down in her heart she always wished to have a soul. But where she comes from, she never will find about it? The voice said : That she will find every single anwer to her questions. She must find an girl with black hair and then she will get all answers when she sees the girl. Arsimina asked : An girl with black hair? The voice said: Yeah the if you find the girl , then you will understand someting about yourself. And you would like to fight for the good and for the light?. So you must an boy with brown spikey hair.His heart is filed with pure light. Arsimina said : How I should find the Girl and the boy if I don´t even know the names of them or how they Looks like this doesn´t help me out. The voice said:Your mind and your heart will be your guide to find them. So you are able to find them and go on a journey to find them. The voice disappeared and Arsimina escape form the Souleater headquarters. And she landed in the world from Hollow Bastion ( Radiant Garden). She was in the libary and readed some books .There she waited for the girl with the black hair and the Boy with the Brown spikey hair.
An Boy appeared , he has Brown hair. Arsimina saw the Boy and walk to over him . The Boy got scared as he saw Arsimina The Boy attacked her. She attacked with her 3 lasers and dodged his attack with teleporting.The Boy was really fast tired of fight against her . Well he could not mess with her because she was to fast for him. Arsimina asked : what is your Name? The Boy answered : I´m Sora and you are not evil? You are a Souleater. You are supposed to be evil? and try to steeling my soul from me? Arisimina explains Sora: That she isn´t evil and don´t steel souls from others . and that she also loves the light. Arsimina also told him: that she must find an Boy with brown hair and who fights for the good and she asked Sora : If he fights for the good side and light? Sora answered: Yes I fight for the good. So you are love the light you wanna fight for the good side. Well it is really strange that a Souleater like you ,loves the light and that wants to fight for the good side. Sora smiled at Arsimina. Arsimina told him: that she gives him missions to prove if he really fights for the good. She would like to go with him and fights the stronges enemies with her help. Sora had no Problem with it ,so he took her with him. But actually Sora wasn´t the one who Arsimina should find , The boy with the pure light was Roxiem. He fight for the good too and he is the one who keeps the balance between light and darkness in one line. He had Brown spikey hair and borwn eyes. Arisimina and Sora flew to Traverse town to find someting about an mystery out. But they don´t know what there awaits them.
Typ: She is a wise Souleater and can speaks, she is really a peaceful Souleater, but she also likes attacks.She attacks Sora with ultra-violetwaves and red ,blue and violet laisers ,the red laser effect are fire attacks,
the effect of the blue laser are attacks poison and attacks ice.
violete the beam effected wind screams and thunder, as well as dimension purple bows in there suck him there.
