She is a powerful cybernetic robot mutant who engaged war many years and trained her to fight when she was 7 years old. Her ultimate goal is to kill Haru Ichinose so she can become a queen, she is the most powerful assasin in Class Black.

Sumireko is the evil, merciless, sadistic, killer and young enough to battle and train with heavy weapons. She is daughter of the CEO of their company and seems to be very wealthy, and all her needs are given to her.

Personality
Sumireko is a spoiled girl, ambitious, arrogant, ruthless, strong-willed, manipulative, sadist, remorseless, vindictive, friendly, sociopathic, egoistic, perceptive, vengeful, flirty, bitter, cold (sometimes), disguiser, and murderer. She's considerably warm-blooded perosnality to people than Tokaku is, but she's hinted to be one of the most powerful and more dangerous members of the Black Class which was proven true later on in the episode 10 of the series, when she revealed her true nature around Haru and Tokaku.

AppeArance
In episode 10, cyborg form she wears a open purple bra with gold patter over it, she wears a purple underwear similar to her bra design.

She has long peach colored hair and icy blue eyes, which are similar to Tokaku's eyes. She usually wears a pink plaid dress with a collared white shirt under it. There is a black ribbon on tied under the collar. She also wears a white vest over it. She wears it with long black socks and white shoes.

Killing Attempt
Sumireko was the ninth person to attempt an assassination attempt on Haru after sending out a warning letter. Her true intentions are not revealed at first, though she is the real big bad to Haru's life, as she gives Haru a letter to a tea party at Myojo Academy's top floor.

She arrives with Tokaku, who Sumireko seems to be annoyed (because she prepared that time to kill Haru immediately), saying she was not invited. Sumireko leads them to a large table on a dining hall, and which dolls of the previous assassins are seated, along with a live Otoya Takechi, who was captured earlier by Sumireko, and is bound by a gag and straight white jacket.

All three girls proceed to take a seat and Sumireko and Haru proceed to make small talk while Tokaku sits by silently. Haru said, she does not wanting to fight anymore, asks if she can grant Sumireko's wish, to which Sumireko replies yes. Her wish will be granted by defeating Haru and proving that she is the strongest queen. Sumireko proceeds to get her letter.

Sumireko begins her assualt by attacking Tokaku with the puppets, which are easily destroyed, but it only serves to distract Tokaku. Meanwhile, Sumireko has a plexiglass wall or indestructible wall descend in order to seperate Tokaku and Haru, to make the latter an easier kill. Thinking fast, Tokaku lassoes a cord around Sumireko's legs, pulling her to Tokaku's side of the wall.

Tokaku then proceeds to fight Sumireko, but is quickly overpowered and thrown into a wall. Sumireko attacks her quickly at close range. However, in an attempt to defend herself, Tokaku picks up a piece of the wall, which Sumireko punches. The impact causes parts of her skin to peel away, revealing her metal beneath her skin. Sumireko begins to flex showing her true metal limbs.

She then proceeds to chase Tokaku around the room, while Tokaku fights her off with a variety of weapons which are knocked away from her, including a knife which lands near Otoya. Freeing herself, Otoya then joins the fight against Sumireko, grabbing a kukri knife off the wall. Otoya's attack surprises Sumireko, but she is able to dodge.

After several attempts, Otoya Takechi is finally able to stab her knife into Sumireko's arm, but Sumireko promptly punched her into the wall. Tokaku, capitalizing on Sumireko's weakened and distracted state, kicks the knife in Sumireko's arm, driving it further in. Sumireko then kicks Tokaku powerful into the wall, detaching her damaged arm to replace it with a machine gun attachment.

Tokaku is again driven into a corner by Sumireko's machine gun arm, but in a quick move grabs a small revolver off the wall, shooting the overhead of the chandelier and dropping it onto Sumireko. She is knocked down, but easily picks up the chandelier and tosses it onto Tokaku. On the other side of the glass wall, now Tokaku is lying down and Haru grabs a rocket launcher, blasts a hole into the door, and runs. Sumireko takes the bait and follows her out.

Haru pretends to take the elevator down, causing Sumireko to forcefully open the door and drop down through the elevator shaft, using her machine gun arm to shoot into the elevator itself. Haru carries back an armful of bunch of grenades, pulls the pins, and drops them into the elevator shaft, where they explode around Sumireko.

However, Sumireko has survived, however, by climbing out. She chases Haru to the roof of Myojo Academy, where Sumireko's limbs are shown to be damaged. Thinking she has Haru cornered, Sumeriko launches her razor sharp nails at Haru.

The nails are attached to metal wires but Haru dodge it and they miss Haru and wrap around the railing of the academy's roof. With the wires wrapped around the railing, Haru tackles Sumireko, pulling both her and Haru over the roof's edge. With both of them hanging off the nail wires, Haru then kicks at Sumireko's machine gun arm attachment repeatedly. Sumireko is summarily detached, falls through the academy's roof, and breaking the glass of the school and fails her assassination attempt, leading her to be the eigth person to be expelled from the Black Class.
