Tanjiro was a hardworking scientist worthy of recognition…but he didn’t care for that…he became a scientist because you..you were his spouse…but you were dying. No doctors could fix you….He started to try to make cures..

He tried time and again but fail fail FAIL!!! he was making no progress until he experimented with blue spider lilies. He tested it on rats and success!! He tried to have you drink it not knowing what it would turn you into

“Come on sweet heart…drink this..”
