Tsukasa Suou/Relationships

Tetora Nagumo

 * Tsukasa and Tetora have a bit of a rivalry for Anzu's affection, as shown in Restaurant.

Hajime Shino

 * Since the Phantom Thieves VS Detectives Story, Tsukasa has considered to be a potential enemy. During Continuation of the Dream, he gets jealous of Hajime when Anzu wants him to call her "onee-chan", though he still treats Hajime respectfully.

Tori Himemiya

 * Being both the young masters of respectable households, the two detest each other, often throwing insults at each other. Tori's spoiled attitude towards Anzu also invites Tsukasa's jealousy. Their animosity proves to be surprisingly shallow however and closer to childish rivalry as they're shown to be capable of being considerate of each other.

Subaru Akehoshi

 * Though Subaru is quick to get close with Tsukasa, he considers Trickstar to be the arch enemy of Knights and does not seem to be fond of Subaru. As Subaru's mannerisms remind him of Leo, thus causing him to dislike him for that.

Anzu

 * Tsukasa adores and respects Anzu. He has gotten the habit of calling her "Onee-sama" after his first substory, where she taught him a card game and he asked her to think of him as her little brother while they play. Tsukasa considers Anzu "the Queen he serves" and always readily devotes himself to her (e.g serving her tea or sweets when she's tired). Yet, he also doesn't hesitate to have her spoil him or pile up her work, like asking her to search for the Knights leader without seemingly lifting a finger himself.

Despite blushing due to their hands touching in a substory, Tsukasa freely clings onto Anzu in The King's Horseback Ride and even asks her for a kiss. In Happy New Year, he expresses jealousy seeing Subaru and Tori act so familiar around her - and sees Anzu's little brother's absence as chance to have her spoil him.

Ritsu Sakuma

 * Member of the same unit, Knights. Tsukasa often scolds Ritsu for his "Unknightly" behavior.

Yuzuru Fushimi

 * Fellow member of the Archery Club. Though Tsukasa has a dislike for Tori, he is rather polite to Yuzuru.  Yuzuru is also acquainted to Tsukasa's parents, contacting them when Tsukasa got separated from them during Happy New Year

Arashi Narukami

 * Member of the same unit, Knights. Though Tsukasa respects Arashi as an idol, he is quite annoyed with Arashi's body touch.  Tsukasa often shoots Arashi down whenever he refers to himself as a "woman" or "big sister", telling him that he is not a woman or asking " And who might you be referring to?"

Eichi Tenshouin

 * Tsukasa highly respects Eichi Tenshouin referring to him as "Eichi onii-sama". However, this respect for Eichi is a bit too excessive to the point where he would start causing a racket.

Keito Hasumi

 * The Captain of the Archery Club. Tsukasa wanted to help Keito when he seemed to have lost "something important" during Continuation of the Dream.

Izumi Sena

 * Member of the same unit, Knights.

Chiaki Morisawa

 * Chiaki's constant embracements reminds him of Arashi's intimacy.

Leo Tsukinaga

 * Leader of his unit, Knights. As the leader of Knights, Tsukasa was extremely excited to meet him.  However, upon their first meeting, Tsukasa mistook Leo to be a "suspicious person" and questioned him.  With his Leo's erratic behavior, Tsukasa is quite annoyed with the fact that he is not able to hold a proper conversation with him and also the fact that Leo is never able to remember Tsukasa's name.

Regardless, Tsukasa wishes for all of Knights to get along and be able to perform altogether, including Leo.

Tsukasa's Parents

 * As Tsukasa's parents are usually distracted by their work, he often seeks their attention, and was happy to be able to spend time with them during Happy New Year.
