Canon
Akito and Airi met in middle school, but they now attend different schools. Akito goes to Kamiyama High School while Airi goes to Miyamasuzaka Girls' Academy, and Airi is a year above Akito. Airi is childhood friends with Akito's older sister and would sometimes greet Akito when visiting her house. Airi also requested for Akito to look after his older sister back in middle school. Airi often has positive things to say about Akito, and she found that Akito, just like his older sister, just can't leave people alone.

Akito and Airi have an area conversation in Scramble Crossing. They run into each other, and Airi says it's good to see Akito. Akito thanks her and brings up that he heard Airi formed a new group and returned to being an idol. Airi explains that a lot happened from when she quit being an idol to the present and that she made a lot of people worry about her. She mentions that Ena never brings it up when the two talk and asks if Ena is just being nice. Airi and Akito both apologize, Airi for making things awkward and Akito for the way Ena behaves. Airi tells Akito not to worry about it, and she thinks to herself how Akito is such a good little brother.

Quotes
"At the same time, Akito's such a good little brother."

Kanatsuka
 Kanatsuka is the het ship between Kanade Yoisaki and Tsukasa Tenma. AKA: Tsukakana

Canon
Kanade and Tsukasa are the leaders of their musical groups, 25-ji, Nightcord de. and Wonderlands x Showtime respectively. They have completely opposite personalities, as Kanade is very soft-spoken and Tsukasa is very loud, to the point where his voice can approximately reach the loudness of a train on an overpass.

Although they are so different, one of the things that "links" them is that they both have an ill relative (Kanade's father and Saki) who caused them to pursue their dream. In Kanade's case, her savior complex developed after her father's collapse and she started composing franctically in hopes of saving other people with her songs. Meanwhile, Tsukasa's ambition of wanting to become a world star in order to make people smile with his shows came from the desire to make Saki smile, although he had initially forgotten about it.

Singing Among the Cherry Blossoms
The two first met in Episode 8, when Tsukasa claims to be late for show practice and bumps into Kanade. The two start a talk. Tsukasa looks rather calm, until he remembers he's late. He returns to his usual self and apologizes. Kanade thinks he's a loud-mouth.

Scramble FAN FESTA
The two don't interact in the event story, however, their upgraded event cards look very similar, they could match.

Fanon
Due to a lack of interactions, in the Western fandom Kanatsuka is considered a rarepair. Still, a small part of the fandom (who "isn't too busy" hating on the ship and promoting RuiKasa or Kanamafu instead) seems to like the ship due to Kanade and Tsukasa being leaders, somehow sharing a dream and similar traits (making people smile with his shows/saving people with her music, both are hardworkers to the point where she forgets to eat and he gets sick), and their possible sun/moon dynamic.

On AO3 it is the most written het (and the fourth overall) ship written for Kanade, with Tsukasa's being Tsukaemu. However, in the Eastern fandom the ship is more supported, as there are around 175 works on Pixiv.

Mafukasa
<div class="mw-collapsible mw-collapsed" data-expandtext="show" data-collapsetext="hide" style="width:100%"> Mafukasa is the het ship between Mafuyu Asahina and Tsukasa Tenma. AKA: Tsukamafu, Mafutsuka, Tsukafuyu, Mfks

Canon
Mafuyu and Tsukasa have not yet interacted in canon. The two are opposites with Tsukasa being somewhat of a happy clown while Mafuyu is more sad. However, the two also have some similarities. They are the only characters in the game who were solely responsible for the creation of their units' respective SEKAIs. They are also both the class representatives at their respective schools. The two also try very hard to live up to high expectations, Mafuyu trying to live up to her parents' expectations and Tsukasa trying to reach the goal of becoming a star.

Fanon
Mafukasa is somewhat popular, mostly in the Eastern fandom. Mafukasa is mostly rivaled by Kanamafu and RuiKasa, Mafuyu and Tsukasa's most popular ships respectively. A certain part of the fandom believes that, deep down, Tsukasa is depressed just like Mafuyu and that Mafuyu exactly understands Tsukasa's pain. Common theme in fanworks is also Tsukasa trying to make Mafuyu smile. Some find that Mafukasa has an unhealthy dynamic since Mafuyu can't express or show her feelings when Tsukasa tries to get her to smile. But even some people that don't ship Mafukasa headcanon Tsukasa and Mafuyu to be best friends despite the two not interacting in canon.
