Okay, SO!
Time for some info-dumping. This is pretty much the equivalent of introducing a cast before a play.
Koi Kurasachi is a man who has multiple tulpas within his mind, but only two are in the physical plane (I will explain more later.) Most of them he has no idea exist.
As far as he knows only IK and H exist since they are on the physical plane with him and Seiteki is just a hallucination.
I will post info pages of them all soon because I finally glazed my art and added watermarks.
For now though, here's what they look like and you can kinda infer their personalities from this.
ohoho miru you always get me to say some koi lore stuff huh HDAWJKMDAWKDASBMDJAB KEEP IT THAT WAY
KOIS FAVORITE COLOURS ARE EVERY COLOR TO EXIST /hj
she thinks all the colors are great! she loves using a BUNCH of colors to do her stuff, but you can see a preference for aqua green and salmon (her usual pallete) OR blue, yellow and red (take the no lullaby - siamés clip for an example!).
a little bit of koi lore under the cut involving chamber
Koi does not get along with Chamber like... at all
he is one of the only people from the protocol she genuinely does not like: if prompted to, she can work with him just fine, but she draws the line in befriending him. His intire personality/allarming mannerism is something that alerts her a lot, she simply knows this man is up for no good! she's very protective of her friends, so when it comes to Chamber, she just gives him the cold shoulder all the time.
he is very interested in her, though: Koi's potential as a radiant is very well seem and her hardwork is undeniable, but her ingenuity and how gullible she can be is something to get worried about. Chamber obviously knows about that and.. just like Reyna, what if he used that in his favor? too bad for him Koi does NOT trust him the same way she trusts/follows Reyna and Sage, yet, he keeps trying to get his offers to her mind sometimes.
She could maybe be part of his bigger picture, but there are a lot of steps to be taken, yet.
An ancient tale from the Orient tells of a huge school of golden koi swimming upstream the Yellow River in China. Gaining strength by fighting against the current, the school glimmered as they swam together through the river. When they reached a waterfall at the end of the river, many of the koi turned back, letting the flow of the river carry them away. The remaining koi refused to give up. Leaping from the depths of the river, they attempted to reach the top of the waterfall to no avail. Their efforts caught the attention of local demons, who mocked their efforts and heightened the waterfall out of malice. After a hundred years of jumping, one koi finally reached the top of the waterfall. The gods recognized the koi for its perseverance and determination and turned it into a golden dragon, the image of power and strength.
