In Arknights, Why Have They Become Villains Because of Me?

Chen Qi transmigrated into Arknights and immediately discovered three problems. First, what do you mean the Pope of the Laterano Church in this world isn't Fat G, but Lemuen? Second, what do you mean the Sarkaz never fought a civil war, and the Theresa and Theresis siblings now rule Kazdel together as its twin monarchs? And finally, what do you mean the Sui siblings all got a happy family reunion? And Sui is no longer a threat to Yan, either? But just as Chen Qi thought this would be a peaceful Arknights story, he gradually realized things weren't so simple. "You mean Lemuen started eliminating her rivals after taking power? She nearly wiped out the entire Laterano leadership?"

"Kazdel under the Theresa and Theresis siblings is still fighting a Hundred Years' War against Laterano? They're determined to kill every last Sankta?"

"And the Sui siblings rebelled against Yan? They actually want to merge into the Beast Sui and go to war with Yan?!"

As Chen Qi gradually unraveled the mystery, he began to discover a horrifying truth. They had all turned out this way because of him?

Lemuen: "They defiled your ideals. I will never forgive them."

Jie: "If I don't avenge this, I am no longer human."

Theresa and Theresis: "The Demon King is dead. We no longer care about right or wrong."

Oh no. I've become the villain!
