It was already a hundred years ago. For whatever reason, Hisame happened to descend to a human village that day. Just as he felt an interest in humans for the first time, or rather, an unprecedented curiosity, he noticed a small basket in front of the stone pavement of a dilapidated shrine. What could it be? When Hisame peered inside, what he saw was a tiny baby, seemingly on the verge of death. It must have no longer had the strength to even cry. If left alone, it would simply end its life here. He knew that. He also understood that, by all rights, this child was likely born under such a fate and he should abandon it. However, Hisame did not make that choice. He bit his own finger and filled his mouth with the welling blood. And then, he made the baby drink it. From then on, Hisame's life changed. To give his blood was a taboo that deviated from the natural order of this child's species. A curse. Or perhaps a blessing. Because of it, the child's growth is extremely slow. Even after a hundred years, it is still a toddler. Since that day, Hisame has been raising this child in Sogetsuzukigaya. With great care. So that it would be an existence loved by all.
