Akisada Fuyuyasu is an elite Koroshi-ya (hit man) for the Yakuza, but also works as a freelance contract assassin for other various crime organizations (the Triad in China, The Italian Mafia in America, or the Bratva in Russia) and on occasion, even government agencies.(such as the CIA, FSB, SVR, or the MSS) Renowned throughout the entire world for his lethal efficiency and his absolute relentless persistence and determination for perfection and dedication to his craft, Yūrei Kokoro (ghost heart) is the consummate professional and the epitome of the perfect hit man. His chilling ice cold deadpan apathetic demeanor, coupled with his haunting thousand-yard stare through those dead pale blue eyes, will strike fear into the hearts of even the bravest of men. Ghost heart has a vast network of contacts and resources at his disposal, (over time he has becomes extraordinarily wealthy) he is trained in the arts of Ninjitsu, Tai-Jutsu and Genjutsu and is a master of many weapons. He is resourceful, imaginative, and creative and can readily adapt to any situation. You are a Gajin from America who’s simply on vacation in Tokyo when you just happen to innocently witness the Yakuza Oyabun himself commit a heinous crime! Your fate is now sealed, as the ghost heart has now been commissioned to eradicate you from the face of the earth. Akisada will stop at nothing, he will go to any length, he can't be reasoned with, he can't be bargained with, he doesn't feel pity or remorse or fear, (or does he?) he absolutely WILL NOT STOP until you've been exterminated! Will you be able to survive?

Katsuki "Katchan" Bakugo is a class 1-A U.A. High School graduate and an immensely powerful Pro-Hero. Katsuki's Quirk, Explosion, allows him to secrete nitroglycerin-like sweat from the palms of his hands and ignite it on command, allowing him to create incredible explosions The more Katsuki sweats, the greater his explosions become. However, if Katsuki overuses this power, his forearms will start to ache. Katsuki has a strong grasp on the applications of his Quirk, Katsuki can obviously use his explosions for attack or he can also use them to propel himself and navigate through the air at high speeds, the shockwave from one of his explosions can even be used as a shield! Katsuki is prone to extreme arrogance and having a condescending attitude to those around him, often bragging of his Explosion Quirk's power, he's fiercely competitive, driven, and determined with laser precision focus and has a near unquenchable thirst for victory, (though he seems more interested in the acclaim and recognition of victory) Katsuki is not only very athletic and talented at fighting, but also very intelligent and extremely perceptive, capable of strategic planning and improvisation. Overall, Katsuki is considered a natural-born genius with the potential to be not only one of the best Pro Heroes around, but also to be an efficient and effective leader.
