episode 135 has so much symbolism that once you understand it more it makes this episode way better
so the entire gungi match was a reflection of this entire operation that the hunters came up with.
So as they are playing gungi, komugi uses Kokoriko (A gungi technique) Kokoriko, this technique is to win the game by making the king piece isolated Just like Netero and the Hunters were planning to do to Meruem in this operation as netero took meruem to an isolated place to kill him
(King piece=Meruem)
Remember Meruem used kokoriko in episode 104 but komugi tells Meruem this Technique is Shiro (Road to Death) Isolated King must die
this reflects the Bomb Netero used to kill meruem but then Komugi shows Meruem a new Technique To Save the isolated king in episode 135
it means isolated King doesn't have to die, Now this reflects meruem surviving the bomb, in reality meruem wasn't killed by the bomb but after komugi uses that technique to save the isolated king, Meruem counter attacks her new
move that saves the isolated king so the new move meruem used to counter komugi is saying that isolated king must die
after all (By Poison) basically saying he can't change his fate no matter what, he will always end up dying
But then Komugi finds a new Counter attack to the one meruem used and said i'll go with you meaning king is not alone anymore, So as Meurem is still trying to win he can't win even once (Meruem couldn't beat kokoriko) it means kokoriko is not not shiro road to death anymore, meaning komugi saved the isolated king
which was beautiful showing that during this whole match meruem was trying to win against Komugi to basically die alone, finding new moves to win, he was trying so hard to die as kokoriko (An isolated king) but komugi manages to save the king each time and in the end, she saves the isolated king
so after this Meruem and komugi start one final game a game that they never finish. 1-5-1 Black King -> 9-5-1 White Lieutenant
General, Immediately afterward, they die together, leaving on the board Meruem's one black piece and Komugi's single white piece, together in Gungi forever.
This represents that the two were always united through Gungi, and will continue to be together even after death, undisturbed and united for all eternity. Meruem places his piece down, symbolizing his death, and then Komugi responds by placing her piece down next to his, showing that she is perfectly willing to die at his side.
so after all this, it shows us he lost everything but gained what he truly wanted. He didn't need any soldiers, palace, countries, power, strength, even his sight(as Komugi) He just wanted to play Gungi with Komugi.
This is the same for komugi too. She had nothing besides Gungi. Nobody loved her, her parents treated her like shit and nobody was nice to her and she couldn't play Gungi as well as she did because she was so good at gungi no one could even match her, She was lonely, Gungi King(Queen?). But she gained Meruem. That's why she cried when meruem counterattacked her new kokoriko. She once needed to create and kill tactics on Gungi by herself. But she gained the perfect opponent and can create tactics with him(I guess to create tactics suggests to create a baby as she said kokoriko is her baby.)
Now the black scene towards the end where we could only hear their voices and meruem asking komugi if she is still there is the Rose's poison, it made Meruem go blind. That's why he has to keep asking Komugi if she's still there because he can't see her anymore. This is ironic because Meruems name means "the light that illuminates/shines upon all". He even got some godlike light-related photon-based powers before his death, allowing him to fulfill his name.
In addition, as they are playing in the bunker before their deaths, Meruem sees a blinding light radiating from Komugi as she "reverses his reversal", making her "the light that illuminates even the all-powerful light".
Despite being far weaker (and blind to boot), her light shined far brighter than Meruems. Then, as Meruem is slowly dying Komugi holds him and feels his head, allowing her to finally "see" or know what his face is like. Thus, as they die, Meruem joins Komugi in blindness as she joins him in death. Meruem can finally see what Komugi has been seeing all along, and knows what it feels like to be blind like her, and Komugi finally knows his face, allowing each other to understand the other more as they fade away (the OST used during their death scene is called "Understanding").
