Talk:Demon Slayer Mark/@comment-44233167-20191025134855/@comment-37768377-20191029161026

Thanks for reminding me of the ability. Tanjiro was already able to gaze through the see through world, without closing off his senses in the battle against Hantengu. I think that a Demon Slayer Mark is a precondition to gaze into the see through world. As for Tanjuro, there are hints that the birthmark Tanjiro and he used to be, were inactive demon slayer marks. Tanjiro has gained his mark after he protected his little brother from a heated boiler, which probably activated something inside Tanjiro. We will see that heat is a precondition to awaken the Demon Slayer Mark, so i guess Tanjuro also had one. However this is much theorizing. Your opinion is definetly not entirely wrong. I guess we'll wait for further information till we create a new page.
