OuMugi

Oumugi is the het ship between Meruem and Komugi from the Hunter x Hunter fandom.

Canon
The two of them meet when the Chimera Ant king Meruem forces a blind girl named Komugi, the world champion of a board game called Gungi, to play against him. He is unable to beat her a single time. The two develop mutual respect for each other as they continue playing. Meruem's royal guards acknowledge that the King has more patience with Komugi than anyone else.

Meruem later saves Komugi from being attacked by a bird and questions his feelings towards her. He also becomes enraged when Komugi is severely injured during an assault on the palace, and Neferpitou risks its life to heal her because of how important she is to the King. After being healed Komugi desperately wants to know where Meruem is and becomes angry when no one will give her an answer.

Near the end of the arc hearing Komugi's name is all it takes to cure Meruem's amnesia from his resurrection. Aware that he has been poisoned, Meruem says he'll do anything to spend his final moments with Komugi and the pair reunites for one final Gungi contest. Komugi is overwhelmed by happiness and both of them believe that they were born for this moment. Meruem tells Komugi to leave so the poison doesn't kill her too, but she stays so she can die with Meruem. At his request she calls him by his name as he dies in her arms. At the end of the Election arc they are shown holding hands in death.

Fanon
Oumugi is easily the most popular het pairing in Hunter x Hunter and is shipped to some degree by most of the fanbase.

Before their deaths, Komugi says to Meruem "I may not be much, but please, let me accompany you". This is an old-fashioned way for Japanese women to accept a marriage proposal. The fact that Komugi used it, leads some shippers to believe they were an official couple or even that they got married. However, romance between the two was never explicitly confirmed.
