Tsuyu/Relationships

Tenjin
According to folklore, Tsuyu adored Tenjin so much that as a plum blossom tree, she had flown to follow him in exile. Not only does she love him, but she has served as a protector to his shrine through the centuries they've spent together. In the manga, she took action to defend the shrine from a masked phantom that had snuck its way in by using a human child as its vessel.

Tsuyu fully accepts Tenjin's nature, despite how she was at times saddened by his spirit of aggression and his violence toward humans.

Tenjin seemed distraught when he decided he must wager her life during the Covenant, although Tsuyu was completely accepting of his choice. He showed great sadness over her death. After the Covenant found Heaven to be in the wrong, he was overjoyed to see that she was revived.

Sakura
Sakura was one of Tenjin's Shinki before he revoked her name during a fit of madness. Despite the severed ties, Tsuyu was sympathetic and acted a sisterly figure to her. It's shown that both cared for each other, to the point that when Sakura ran away from Yaboku, Tsuyu is the one that gave her advice on guiding a God.

Mayu
Tsuyu and Mayu have a friendly relationship, and look out for one another as fellow members of the Yu-clan. Since Tsuyu cannot create a Borderline, Mayu stepped in to dispose of a phantom that was threatening to attack Tsuyu. Tsuyu also shushed Hiyori in order to protect Mayu from being touched by the God's Greatest Secret.
