Flash facts! Special edition! Creators notes and thoughts

•In case you haven't noticed, Shu is albino. Down from her eyes to her hair to her skin and even to the color of her tail. I designed her this way to add a edge to her character. Despite being pale and white, which to others comes off as beautiful, delicate, and innocent, the pale color is to represent how dangerous she is. As unlike her father, who relies on ambush and shock value to strike an enemy, she's clear in the open and easy to see. Despite that, her accuracy rate and success rate is 10x higher than her father's.

•Shu doesn't have a fish species. Unlike her siblings, even her father, who represents a anglerfish. Shu doesn't have a defined species. Although in early drafts she was an anglerfish Siren. I cut that out to keep her in one defined lane.

•A few years ago, Shu didn't even have a Siren quirk. She was actually a nekomata yokai. However, I found the stereotype of a Neko OC in MHA overused and unoriginal. So I changed her to a Siren.

•Shu original had a child with Reiketsu. Who's name was Mio. However I changed that to fit more realistic, as I found the idea of a 14-15 year old having a baby to be unnerving. Instead Mio is Shu's late cat.

•Shu was originally meant to have a split personality disorder much like her older late siblings. Where Shu was stuck between morality and her Siren urges. However that was cut out because it felt like she was giving main character pick me energy. However, I kept around her Siren urges in the form of impulses.

•Shu was meant to be a ninja and her original weapons was a oversized shuriken. And that's how she got her name Shu. However, a Siren and shuriken didn't mix. I did keep around the fact she's raised by ninjas and has a level of ninjitsu training.

•Sylvester was actually meant to be Shu's twin brother. Where she had albinism, he was melaninistic. However that was cut later and switched to cousins.

•Shu's fins and tail used to be a deep blue, or even a deep dark pink at one point. However, the colors clashed badly with her pale color scheme and it made no sense that a albino had dark and black tones to her quirk. So I changed it to be white and pale.

•Shu's arc did not start the moment she met Shinso. Rather before that. Her arc from the time she was 15 to 16 was triggered by her cousins who forced her to get help. By the time she met Shinso, she was already at a point of stable. And while she still had issues, Shinso's presence made it easier to continue getting better.

•I originally intended for Shu to be a representation of serious topics including SA and consent. However, that was changed due to said topics being too heavy to write and properly execute. Shu still represents topics of unwanted attention and the issues of being pretty, however to a tame degree.

•Much of Shu'a old characteristics transferred to Wagamama. Such as personality, storyline, and appearance.

•Shu's hero costume is based on the term "Office Siren"
