Iko Koishikawa

"Why would anyone be angry at someone who had done their best to save them? Shy did her best to save me, and she did... Just like you just did, Momijiyama."

- Iko Koishikawa to Teru Momijiyama in "Duty of Heroes".

Iko Koishikawa was saved by Shy during an incident in Himawari Land amusement park alongside her younger brother and some other people. She later transfers to Teru's school since it was closer to her house (as such, easier for her to go due to her injured leg at the time) and became close friends with her.

Appearance
Iko is a beautiful young girl with light complexion and wavy medium-length, blond hair with bright, yellow eyes. She is always wearing a tiara with a crescent moon on the right side. After the incident with the rollercoaster, her right leg was injured, so she had to use a black brace on her right knee and crutches to walk properly. She used to wear her old school uniform: a shirt buttoned with a bow, blazer, skirt, black socks on her calves and Mary Jane shoes.

She eventually received her uniform from her new school: long-sleeved shirt, tie or ascot, skirt, calf socks and loafers. She once wore a layered shirt, knee-length trousers, slip flats, a bracelet on the right wrist and a side bag when hanging out with Teru for the first time. When she told the team of Heroes about her vision of Stigma, she wore a buttoned short-sleeved shirt, pants, shoes and a wristwatch.

While hanging out with Teru for the first time, she wore a layered shirt, pants and loafers with her hair stylized with a braid tied at the back of her hair with a hairclip.

Personality
Iko is a very friendly and outgoing girl who can make friends easily. Unlike Teru, she doesn't have any problems to talk to people and is, actually, very charismatic, drawing attention to herself frequently. She is usually the one who makes Teru hang out with her, in addition to encouraging her in her decisions. Iko also tends to show a lot of concern for everyone except herself as when she tells Shy to save the other before saving herself, resulting in the accident which injured her legs.

It is revealed that, instead of hating Shy for her condition, she hated herself but for other personal motives: these were her parents' deaths, as she couldn't save them. She also didn't feel like she was a good sister to her brother without them. Stigma used his ring to create her corrupted form, outcropping her bad feelings from her Heart. After being saved by Shy, however, she seems to have improved a lot psychologically and is much happier currently, including she could be friends with Teru and is the only one who knows her Hero identity.

She develops a strong sense of justice and is always trying to help Shy even though she herself is not a Hero and doesn't have any special ability like her and her fellows Heroes. Iko feels useless if she is unable to help them in someway, be it with information about the Amalareiks or trying to cheer Shy on.

Since her parents died, Iko has taken care of her brother alone. Due to that, she is very good at take care of children, shown when she was able to calm a lost child at the mall while hanging out with Teru one time, helping him find his parents. Just like her brother, she is also very obsessed with superheroes, easily getting excited when talking about Teru's heroic identity, Shy, as well as other Heroes like Stardust and Spirits.

Iko presents herself as quite perverted at times as she asked Teru if she ever gets naked when transforming with her Heart Conversion Bracelets and voluntereed to record it even if Teru was embarrassed.

Abilities
Efficient Children Care: Because she had to raise her brother alone, Iko grow up to be really good with children. She could easily calm down a boy who was lost and find his parents quickly, at the same time, teaching him an important life lesson.

Former Abilities
Corrupted Form: Using her hartred for herself, Stigma put one of his rings in her finger to turn her into a monster. The ring syncronized Iko's Heart power and Stigma's own Heart. In this form, her hair turns dark and her right arm and leg have a crystallized appearance, five clawed fingers and a birdlike foot with three sharp toes. Her left hand and thigh and right cheek had crystallized fragments. The sclera of her eyes became black and appeared to be bleeding, while a single horn protruded from the left side of her forehead.

In that form, Iko had immense strenght, physical durability, aprimored speed and agility. She could manifest her Heart through crystal-like weapons and attack her enemies with them.

Former Equipment
Stigma's ring: She was forcefully transformed into a monster by Stigma, who put a Heart conversion ring on her left index finger. It had a part of Stigma's own Heart and released Iko's hatred for herself in the form of black crystals made by her own Heart. It allowed Iko to see Stigma's Heart and help the organization of Heroes to think about a way to deal with him and his group.
