Arknights, but the family has fallen again

Carrying the golden finger of Dark Dungeon, Doc Otter came to Terra, which belonged to the beast-eared girl.
By equipping accessories, Ott can establish a spiritual connection with the heroes, enabling the sniper operator to move five centimeters to the left...
Or forcibly break through the mental barrier and seize anyone's body!
He is obviously the protagonist, but he has become the villain boss...
Hey, wait? Goldfinger is Darkest Dungeon?
No "1" as suffix?
That's fine.
Is it strange that the protagonist and the boss are the same person?
Not surprising.
The traces shaped like an iron crown were imprinted all over Terra along with the footsteps of the Rhodes Island land carrier.
Looking back, Ott couldn't help but sigh...
There was a shark who had mistaken him for the "Lord of All Creatures" and who would pretend to be ill from time to time to take advantage of him after waking up; a killer whale who seemed cold but was actually stupid and sold herself to him without knowing it; a self-redeeming dragon girl; a double-faced bomber; a toaster that was too early; a female teacher wearing a collar and tied up like a hawk...
Kal'tsit pretended to be a dynamometer and said: Bread machine, right?
