Tsukiyama became interested in Kaneki due to the aroma, yearning to eat him, and approached him at Kamii University, lured Kaneki to the ghoul restaurant ghoul restaurant, then kidnapped Kimi and lured him to the church, all with the intention of eating him.

The problem starts in the 2nd season, Kaneki, who was kidnapped by Aogiri and tortured by Jason, Anteiku ghouls, Tsukiyama and Uta, went to rescue Kaneki, Shuu still has a great interest in eating Kaneki.

After Kaneki leaves, he became a member of Aogiri, but in the manga, he forms a group with Banjou, Hinami, Sante, Jiro, Ichimi, and obviously: Tsukiyama.

Tsukiyama offered to be Kaneki's "sword", he prepared the hideout, helped Kaneki with information and missions, they trained together, they became really close. Tsukiyama's feelings changing perspective and he became attached to Kaneki much more than just being his food, he used Hinami to try to gain Ken's trust, but it was just a pretext, he really cared about him and wanted to make him happy.
