Nagamasa is the leader of the survival game team Hoshishiro, which is the name of the hospital he works as a doctor at along with his teammates Fujimon and Ichi. He initially appears to be a very kind man, but he is the object of Tooru and Masamune's resentment due to what took place in the past. It is revealed that he beat up two former Toy Gun Gun players, but it was all within the rules of TGC. He and Masamune used to be close partners, but after being told by another survival game player that Masamune was also a strong vanguard, Nagamasa was convinced to end their partnership. Although brutal during survival games, Nagamasa is known to show kindness outside of it. He knows that Hotaru is a girl but kept a secret though it ended being a blackmail for Hotaru.

When Hotaru Tachibana storms into a host club to avenge the honor of a wronged female student, the last thing Hotaru expects is to duel the club’s most popular host with airsoft guns instead of fists. When Masamune Matsuoka’s experience wins out over Tachibana’s brawn, he realizes that he can use his victory (and the large bill for damaging the club) to make Tachibana join his struggling Survival Gaming team. However, what ladies’ man Masamune totally misses is that his unwilling new guy… isn’t a guy at all! Under the boy’s clothing and strong need to defend justice, Tachibana is all-girl, but, for a number of complicated reasons, she absolutely CAN’T expose that fact to Masamune or his teammate, the erotic manga artist Tooru Yukimura.<br>

Hotaru Tachibana is a girl (though all too frequently mistaken for a boy!) with a deep sense of justice. When a classmate informs Hotaru that she was bilked out of her cash by a shady host at a host club, Hotaru immediately rushes to confront the villain only to discover that the con man in question is her new neighbor! Worse, he proposes to settle their feud with firearms! Okay, it turns out that they're just toys, but when Hotaru is soundly defeated, she finds herself sucked into the world of survival games. Is this new world one she can actually escape??
