In Ultra Despair Hagakure light novel, Kanon travels with Yasuhiro, after saving him from Monokumas. She gives him the nickname "Yasu".
After finding out that he's from Future Foundation, Kanon had a desire to kill Yasuhiro. However, he isn't anything like what she thought a member of Future Foundation would be. The more she talked to him, the less she wanted to kill him. However, she attempts to kill him after finding out that he has read her pocketbook.
Kanon sees Leon in Yasuhiro and even though she knows he is a member of the Future Foundation, aiming for her father's money and "totally lame", she eventually realizes that she doesn't hate Yasuhiro and doesn't want him to die simply because of that.
At one point, Yasuhiro saves Kanon from Masaru Daimon and Kotoko Utsugi. While Kanon is less forgiving to the other Future Foundation members, she is ready to give them a chance if they turn out to be good people like Yasuhiro.
Although he makes fun of her Gyaru speech pattern, he starts to treat her like royalty after finding out that her family is rich and might be able to help him pay off his large debts.
Yasuhiro is disturbed and afraid of Kanon after finding out that she is trying to kill members of the Future Foundation. Even after she tries to kill him, he still saves her from certain peril. The two have grown close during their traveling and Kanon admits that she doesn't want to kill Yasuhiro anymore. In the end, Yasuhiro stays with Kanon, claiming that it's for the sake of solving his debt.

This ship isn't too well known due to originating from a side material, a light novel titled "Ultra Despair Hagakure" which is included as a bonus feature after completing Ultra Despair Girls game. Those who know about it tend to prefer it over Kanon's other ship, Lenon, due to Kanon's unhealthy obsession with Leon as well as the two being cousins. It is one of Yasuhiro's ships that is not very well-known in the fandom.
It is also the most written Kanon's ship on Archive of Our Own.
