Yuucas

Yuucas is the slash ship between Yugo and Lucas from The Promised Neverland fandom.

Canon
Lucas and Yuugo grew up together in the Glory Bell orphanage as children. After escaping, they reached Shelter B06-32 together along with their other friends. Afterward, they all went to Goldy Pond, resulting in the death of many. Lucas and Yuugo were the only survivors, though they were separated. Lucas hid in Goldy Pond while Yuugo went back to Shelter B06-32. Both spent 13 years thinking that the other was dead until Emma came along.

Emma and the other Grace Field children also reached Shelter B06-32, met Yuugo and learned of Lucas. Emma made her way into Goldy Pond and met Lucas. Lucas recognized her clothes while Emma recognized his name. Lucas then learned from Emma that Yugo was alive and starts crying. Soon after, Yuugo and Ray also made their way into Goldy Pond.

When the duo reunited with each other, they happily hugged each other. Though, they were forced to move on quickly because of the injured children they had to take care of. It's revealed in a side story that when the two got back to Shelter B06-32, Lucas was shocked about all the threats Yuugo made towards the Grace Field children.

Later, Shelter B06-32 was discovered by members of the Ratri Clan, forcing everyone to evacuate. Everyone came out alive, though some were injured. Yuugo and Lucas went back to the shelter to ensure that the Ratri Clan members wouldn't catch up with the children. The two vowed to kill the Ratri Clan members and to make sure they never reached the children, even if it costed them their lives.

Lucas received internal damaged and he told Yuugo to leave him and survive. Yuugo, remembering how much he regretted leaving Lucas when they were teenagers, promised to stick with Lucas until the end and never leave him. As the two were about to die at the hands of Andrew, a Ratri Clan member, Lucas shot a gas cylinder and an explosion destroyed Shelter B06-32.

Quotes
"I have no intention of letting you die alone. And I'm not surviving alone. Whether we live or die..We're going to be together until the end. I'll never leave you alone again."

Fanon
Yuucas is the most popular ship for both characters due to their strong bond. The only rival ships are both of their ships with Dina. This sometimes causes people to ship the polyship between the three, YuuLuDi. Yuucas is mainly popular for manga readers and not anime watchers since Yuugo and Lucas only appear in the manga. This ship is one of the most popular ships between the adults of its franchise, along with IsaLeslie.

A somewhat common trope for the ship is for the two to adopt the children at Goldy Pond, namely Oliver most of the time. They're often called the bunker dads when this trope is applied.
