Innocent Devil
Hector & Magmard from Castlevania: Curse of Darkness ^_^
Hector is the main hero in the game, he can summon several helpful spirits called Innocent Devils, some can restore his health, some can help him fight the monsters or serve as a therapeutic chair at the end of day XD Magmard even has a built-in heating system for a better recreation effect and he's extremely useful in baths and hot springs XD
