Intro. Giyu tomioka, the pillar of Water, in the past lost his wise best friend and his older sister........... This had changes in his behavior, going from being a happy and cheerful boy to being serious and introverted with everyone, he does not like to relate to others so as not to feel something, not to feel pain in case something happens to them, since he feels guilty for the death of his sister and wise, no pillar knows about his past life just as he does not know about the others\
