@Xhominid The Apex, @Adamant soul Playable characters in Penny Blood: Hellbound are
Clara is a mysterious girl with very little memory of her past and the natural ability to manipulate Malice at will (corruptive energy born from negative human emotions, which has the power to warp and twist humans into monsters). According to Kato-san, she designed Clara as a character too crazy to include in the main game.
Sariel is a former elite soldier who leads the Hellhounders in their mission to destroy the powers that be and change the world. Is strengthened by multiple prosthetic limbs and Malice-infused attachments. Is going to be one of the antagonists in the main game.
Dr. Franz Eugene a genius sociopath scientist who serves as the brains of the Hellhounders and is the reason the Hellhounders have superhuman powers thanks to his research into Malice. Is going to be one of the antagonists in the main game.
Joseph Momfre, the infamous Axeman due to string of serial murders he committed in New Orleans, the Axeman was recruited by the Hellhounders and treated to Malice infusions that boosted his already monstrous strength. Also loves novels and jazz. The Axeman is based on the unidentified serial killer, The Axeman of New Orleans. Is one of the antagonists in the main game.
Darya Nikolayevna Saltykova is A ruthless sadist from the 1700s brought back to life through one of Dr. Eugene's experiments through the power of Malice. And her DNA is infused with spider genes. Long devoid of sympathy and kindness, Darya now has only one goal; to feed the life within her womb with as much Malice as possible and rear it into the most powerful being the world has ever known. Darya is based on the real life murderess, Darya Nikolayevna Saltykova. Is one of the antagonists in the main game.
Vito Andolini was first recruited to the Hellhounders by Sariel due to his marksmanship. But his refusal to undergo Dr. Eugene’s Malice transfusion and become a monster like the rest of Hellhounders has made him the black sheep of the group. Is one of the main party members in the main game.
So basically, Pennyblood really is connected through Shadow Hearts if Roger Bacon's existence wasn't proof enough.
