Sorry, I'm Also a Mechanical Geek!

Because of the blessing from the gods, Kiryuuyu, who was lingering on the bed and in pain, was reincarnated into a different world with ghosts. But something went wrong during the reincarnation process, and one person's soul was born into two people's bodies. When they are close to each other, the highest attributes of the two people will be shared. When they are separated, as long as one person has a breath left, the other person will never die. Bottom line: I'm invincible, to a certain extent. If it were a normal world, he might have lived his life peacefully with himself, but although there weren't so many murderers and bomb demons in this world, there were countless late-night cannibals. So there is such a weird situation - standing in front of you now is a super mechanical monster that will never die no matter what kind of injuries it has. When they are separated, they are absolutely immortal. When they come together, not only do they have a tacit understanding, but their strength is x2 at the same time. In this way, I relied on my invincible immortality skills to become the new Inubashira of the Demon Slayer Corps. By the way, I also adopted a very compatible and good boy as my stepson (Genya gave a thumbs up, and Saneya thumbs down.) Small theater one Ghost: Are you kidding me? Are you really human? I've slashed you eighty-eight times, how can you still stand up? (Some kind of ominous premonition. Jpg) Kiryu's canine: a toothy smile covered in blood. Jpg Small Theater 2 A friend of the Demon Slayer Corps suddenly asked about the reason for joining here. Kiryu Kenga said (seriously): I don't want my brother to be in danger. In a sense, he is my father, my caregiver, and everything I have in this world. Ichiro: "...... Is this why you built a bamboo hut in front of my house and put four beds? Why did you acquiesce that my brother and I will live with you two, you self-righteous person!" Muichiro: Great! (A certain brother: You are also a fool, don't accept it so quickly!) A certain Fengzhu: "How well you protect your brother, why should you involve other people's brothers!" Canine (stiff and unskilled wink. Jpg): "My brother and Xuanya are in the same class." A certain Fengzhu: "..... You deserve to play with Tomioka. You are really disgusting." —————— This is a story about killing evil spirits. The protagonists are me and myself. 1.
