Sounia

Sonda is the het ship between Sonia Nevermind and Kazuichi Souda from the Danganronpa fandom.

Canon
In Danganronpa 2, Kazuichi quickly develops attraction towards the foreign princess, Sonia Nevermind. Unfortunately for him, Sonia tends not to notice his feelings. Even when Soda manages to achieve something (like build a communication device between those in the hospital and those in the motel), Sonia never seems to notice. Furthermore, she usually ignores or scolds Kazuichi. Later on, Sonia's attraction to Gundam Tanaka becomes even more noticeable, visibly upsetting Kazuichi, especially when she chooses to investigate the Fun House at 4th Island with Gundam twice.

In Danganronpa 3/Despair Arc, their relationship seems exactly the same as it was in the Neo World Program.

However, in the OVA, in Nagito's illusionary world, Sonia seems to actually return Kazuichi's feelings. She agrees for a meeting in a cafeteria. After Souda's death, she imminently goes with her other 4 classmates to try to avenge his death by trying to kill the World Destroyer.

In Hope Arc, the finale of Hope's Peak Saga, Sonia finally notices Kazuichi's efforts and praises him after the latter manages to destroy a robot using his Minimarus. Kazuichi is later seen hanging out with Sonia and Gundam on the ship.

Fanon
The ship started back during Danganronpa 2, about as quickly as Kazuichi's attraction to Sonia. A lot of fans liked the ship and rooted for Kazuichi to eventually win the heart of the girl of his dreams. Those fans were happy with their interaction in Hope Arc and their relationship in Nagito's illusory world in the OVA.

However, the ship is much more divisive. Plenty of fans wish his attraction to Sonia didn't take a vast majority of Kazuichi's screentime, especially since it stole the screentime of his friendship with Hajime Hinata. Some also simply got tired of Kazuichi talking about Sonia most of the time. Those fans often tend to prefer its main rival ship - Sondam. However, there are still those who like both ships and can't decide between them, resulting in Sonsodam.
