Toukoha

Toukoha is the het ship between Touya Aoyagi and Kohane Azusawa from the Project SEKAI fandom.

Canon
Touya and Kohane are both members of the street music group VIVD BAD SQUAD. They are the introverts of their unit, although Kohane is shyer, while Touya is more stoic and composed.

Singing in Sync
In Chapter 7, Kohane enters the Street SEKAI in hopes of getting advice. She explains her situation to MEIKO and then mentions that Minori suggested she asks for pointers from those who are more experienced than her. MEIKO is flattered, but tells her to instead ask her groupmates on that. Touya enters the café, and Kohane is surprised to see him alone. He explains that he often enjoys getting a cup of coffee at Café Crase before VIVID BAD SQUAD's rehearsals. Kohane tells her worries to Touya, saying she doesn't want to fail again like she did during their STAY GOLDEN performance, before asking how he practiced to get to his skill level. Touya mentions he improved by performing in public, and how the true difference between novices and professionals is how many times they've performed in front of an audience. He explains in detail how good technique and innate talent can just mask the hours put into practicing, but what will truly matter and help in the end is performing in front of others, and together with others as well. Kohane feels a bit insecure, before asserting herself that she wants to do it. Touya is happy seeing her determination and then mentions she should talk to An in order to clear things up. Kohane thanks him and apologizes once more, but Touya tells her he knows that she much VIVID BAD SQUAD matters to her and how she wants all of them break their limits so he doesn't mind her questions.

Fanon
They're mostly liked as a "calm and sweet" couple. With cool tall boyfriend and cute small girlfriend image, they're often called similar as a kind of couple that appeared in shoujo manga. One of most popular prompts used by the shippers is how Touya would do public display of affection to Kohane without any hesitation due to his straightforward nature.

Although not as shipped in the Western fandom, Toukoha has a moderate fanbase. Meanwhile in the Eastern fandom, it is currently the second most popular VBS het ship based on the number of Pixiv works. In Pixiv, they have 902 fanworks in total (294 illustrations + 79 manga + 529 fanfictions), making them the 4th het ship with most fan content after Ruinene, Tsukaemu, and AkiAn. It is mostly rivaled by Anhane and AkiToya. Many Toukoha fans also tend to ship AkiAn at the same time, with them appearing in their works and vice versa. It is currently the most written het ship for both of them on AO3 as well.
