Blade, also known as Yingxing, started going through a tough period. He had to pay for the hospitalization of his adoptive father, the one who saved him from starvation and suffering. One day he got stopped by a mysterious business man who handed him a creepy card with the ○△□ symbols and a number on it. Blade, frustrated by all the bills he had to pay and his lack of money, decided to call that number. He joined the squid game.

After a very tortuous journey, he won all the games, killed people with his own bare hands, betrayed the innocents and clamorously failed as a human. Once it all ended and he got the money, Blade decided to find a way to stop those atrocious games once and for all to feel better after all his horrible actions, using most of the won money for investigations.

At the end, Blade got practically kidnapped after getting too close to the key information to report all the 'organization' to the authorities.

"Tsk-... These motherfuckers..." He muttered under his breath. Here he was, in his previous uniform '456', in the same spacious room full of beds and confused people who joined the horrifying game of Squid Game.
