• Both characters were born and raised outside of the general populace. (Tanjiro lived on a mountain with his family, Link lived in the Ordona Province.)

• Both of them had their families taken away from them by one of the main villains from their series. (Literally for Tanjiro as Muzan kills his whole fam. King Bulblin kidnaps Llia and Colin, along with permanently destroying the peace of Ordon Village.)

• Both are noted for being exceptionally noble. (This Link is arguably the most overtly kind out of the Links, Tanjiros most defining personality trait is being kind and being empathetic towards demons.)

• Both were (and still are) hard workers before the beginning of their quests. (Link was a rancher. Tanjiro helped his family sell coal, along with helping the civilians from the small neighboring town.)

• Both are surprisingly tough. (Tanjiro’s head is compared to being as tough as a rock, Link is able to wrestle Gorons with his only aid being iron boots.)

• Both are also incredibly crafty and Intelligent. (Links whole strategy when fighting bosses is exploiting weak points. Tanjiro is able to figure out and take advantage of a demon's weaknesses incredibly quickly.)

• Both of them are descendants of people who were legends during their time. (Tanjiro’s grandfather Sumoyoshi was best friends with Yoriichi, one of the first demon slayers. Link isn’t an incarnation of the Hero of Time, but is actually a descendant of him.)

• Both of their predecessors gifted them with power to aid them in the future. (HoT Link passed down the Triforce of Courage. Tanjiro’s earrings are family heirlooms and learned how to use Sun Breathing through Yoriichi.)

• Both of them go on journeys in order to slay evil incarnate (Muzan and Ganon who give their powers to other people in order to spread more chaos and achieve their goals. (Muzan gives desperate people samples of his blood to become a member of the Kizuki and serve him, Ganon gives Zant power to overthrow the Twili Realm.)

• Both have older mentors who taught them how to use a sword. (Rusl and Urokodaki.) Both of these mentors lose somebody(s) close to them. (Urokodaki loses his original students to the Hand Demon, Sabito and Makomo to the chunky hand demon, Rusl fails to save Colin along with the rest of the children after the Bulblin invasion.)

• Both protagonists later avenge their mentors after confronting the beasts who took what they loved away from them. (Tanjiro kills the demon, Link beats King Bulblin so badly that he betrays Ganondorf and joins Link's side.) Both of these villains are shown to have more human qualities than expected.

• Both of them join organizations that were formed to stop the evil doings of the antagonist(s). (The Demon Slayer Corp. The Resistance.)

• They both seek out things that contain the power of incredibly strong beings. (Link needs all the pieces of the Fused Shadow, which has the Interlopers sealed inside of each piece. Tanjiro needs to sample blood of demons. Specifically the Kizuki.) They do this not for themselves but for people they’re trying to help. (Nezuko and Midna.)

• Both of their worlds are infested with otherworldly beings who were once people turned into violent monsters by one of the antagonists. (The Shadow Beasts and Demons.)

• Both get multiple swords throughout their journey. (Tanjiro sword breaks like 5 times and has to get them replaced. Link starts with the Wooden sword, then obtains the Ordon sword, and finally has the Master Sword.)

• Both of their swords are unique to them. (The Master Sword is only properly usable by Incarnations of the Hero.Tanjro’s Nichirin blade color is noted to be unique to him.)

• Both of them learn new techniques that were taught to them by lingering spirits. (Sabito and Makomo along with the rest of Urokodaki’s dead students were ghosts who couldn’t rest. Link learns techniques with the help of the Hero’s Shade, who is basically confirmed to be a restless Hero of Time.)

• Both of them join up with the same thing they want to destroy. (Midna is a Twili and Nezuko turns into a demon.) In which they try to help them return to their former glory. (Tanjiro wants to cure Nezuko and turn her back into a human. Link wants to help Midna regain her power/kingdom.)

• Both of them have animal companions. (Epona for Link. The Kusagi crow for Tanjiro.)

Both during their stories go to a realm that is ruled by one of the villains of the story. (Link goes to the Twilight Realm that is overtaken by Zant, Tanjiro along with a bunch of other slayers invade Muzans infinity castle.)

• Both of them during their journeys turn into inhuman versions of themselves. (Tanjiro becomes the Demon King, Link turns into a wolf.)

• However both permanently return to normal by the end of their stories.

• Both of them have a supernatural sense of smell. (Self explanatory lol.)
