Plot:

In the blink of the mind's eye, Ryouta Sakamoto suddenly finds himself transported from playing the hit Btoom! video game to being stranded on a mysterious island, equipped with a day's worth of provisions, a bag of bombs, a strange crystal embedded in his left hand and a huge gaping hole in his memory. But it doesn't take long to figure out what's going on, especially after the first person Ryouta meets tries to kill him. Someone is attempting to recreate the ultra-violent Btoom! game in real life, and the island has been filled with an army of other unwilling players, each armed with one of the multiple variants of explosive weapons called BIM. Fortunately, Ryouta's an ace Btoom! player, but this insane version of the game has no reset switch or second lives, and there's only one way off the island: kill seven other people before they can kill you! Can Ryouta repurpose his game based skills fast enough to survive?

Himiko is a Btooom! player and the female protagonist of the Btooom! manga series. She has a crush on Sakamoto and cooperates with him in the Btooom! game. Her real name is Hemilia.
Himiko is a young high school girl. She has bright blue eyes and long, blonde hair, making her look like a foreigner. Her hair is wavy and parted to the right, exposing a part of her forehead. She has small earrings and paints her finger-nails cyan. She has pretty large breasts. Because of her events on the island, she is also covered with small bruises and cuts.
She has only been seen wearing her high school uniform. Her uniform consists of a white buttoned shirt with a small tie around her neck. The tie is dark green and Himiko styled it with an embroided white skull. She also wears a camouflage-colored skirt, that reaches the half of her thighs. She has black, long socks and regular shoes. When her underwear was exposed, it is shown that she wears pink bra panties.
When she and Sakamoto stayed in the deserted building together, she began wearing a white shirt she found in the rations-case. The shirt has a print of a bat on it and reached over her skirt, revealing only a small portion of it.
