The Indomitable Master of Elixirs - Chapter 170 - Teaching Bad Dogs a Lesson (2)

In regards to the MMORPG Cross Reverie, Sakamoto Takuma boasted an overwhelming strength that was enough for him to be called the Demon King by the other players. One day, he gets summoned to another world with his appearance in the game. There, there are two people that insist “I am the real summon master.” Takuma gets slave-turning magic used for summoned beasts cast on him by the girls –

Shaymon, the man who has achieved the apex of dark magic, is framed as being a Demon King and is killed.

Following the death of his popular online persona, seventeen-year-old Suzuki Mato decides it's time to retire from professional VR gaming. However, his plans are abruptly cut short when he's kidnapped from his high school and forced to be a guinea pig for Genaco Gaming, the world's largest esports and entertainment company. Armed with nothing but his wit and a new online persona, he's thrown headfirst into the virtual reality of “Live No Evil,” a VRMMORPG littered with overpowered bosses, secretive NPCs, and backstabbing gods. His mission? Find a way to conquer this new world and get back at the company that took over his life, all while avoiding 'Parallel' -- a condition that would make it impossible to separate his real and virtual personalities. Because in a world obsessed with VR gaming, Parallel means death, and Suzuki just doesn't have time for that...

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.
