Development:
Izami pieces was originally developed as one of the first students ever created for the magic academy, she was meant to be one of the characters who would be in the story from beginning to end serving as a voice or reason and sometimes a voice of chaos. There would be other characters like her such as kirami, who came shortly after, mirato, who would come much later but would initially much more complex, and Chelsea, who was the latest in this line of character archetypes and would serve to justify changes to both izami and kirami. Shortly before the release of the "lets fall in love on the beach koto koto" event izami and kirami both went through a series of changes in terms of origins, abilities, and in izami's case, personality. Izami's personality was changed to be much more chaotic and less thought out, she was made more selfish and shown to have goals that more aligned with herself and not the main character. These goals weren't anything that could cause her to go against the player but it separated her form the player similarly to how the other three already were.

Origins
Much of izami's original origin story hasn't changed, she is still the daughter of Gabriela Pieces, a character from the first magic academy who had a recurring role as the weapons master of the hunters of Catherine. Izami didn't have much of an origin outside of that but that was remedied during the massive change to a lot of characters right before the summer event. Izami was changed to be the daughter of Gabriela pieces and an, as of right now, unidentified demon male making izami a half-breed.  Gabriela wishing to hide her demonic heritage from izami after the betrayal of her demonic father, had Mira seal away her demon powers until she would need them most.  This however had a negative effect as it caused the spiriton record to put more importance on her than others which is what resulted in her being drawn to the magic academy.  Chelsea Niblet would sense that a large amount of energy was gathering at the magic academy and part of that would be from izami who had been chosen as the host for the grand summon shiva.

Abilities
Izami's original set of tools was quite limited and was another reason for her change later in life, she had access to metal and electric magic but her mana reserves were (and still are) quite low. To augment this she had 2 hidden abilities the first was called light smith which allowed her to absorb light and then fire it off in various ways however this would leave her exhausted if she used it too much, the second was called the inventors eye which let her see how any pieces of machinery was built and would help with primary form of combat, magic weaponry. Izami mainly fought with special inventions that channeled mana to get them to work this included everything from small metal Bombs to jet boots. After her changed she gained 3 major new abilities, the first was access to the grand summon shiva would serve as her greatest weapon, she was able to fuse with shiva in certain situations but most of the time shiva was summoned for one big attack and then sidelined for the rest of the fight. The second of her abilities was the demonic transformation which she would only gain partway through the story, this transformation increased her mana supply permanently and gave her access to all kinds of new tricks putting her on the same level as the other 3 companion characters. The third and final new ability that was added to ability was dark summoning, dark summoning would allow her to fuse her demonic powers with shiva essentially corrupting her and then fusing together with shiva to take her powers to all new heights, this form can only be achieved when she really needs it as she has yet to master it

And that's all for the development, origins, and abilities of Izami pieces next up to get a chapter like this will be kirami, Mirato, or Chelsea, I haven't quite decided yet.
