Redeeming the Villain, but Bound to a Fluffy

[There is a group of villains who are dark and brutal, evil and obsessive. But they were once the darlings of heaven, dragged down into the mire. They once longed for the light, but the moon hung high in the sky and never shone on them. In the end, they took the whole world down with them. The Host's mission is to change their hearts with love and save the world! Complete the mission, and the Host can be reborn and rise to the pinnacle of life...]

The Host tilted its head in confusion: ...Wer?

[...Crazy?]

The System crashed. Repeated restart attempts failed...

At last, it let out a piercing shriek: [...Why isn't my Host human?!]

World One

Mika couldn't understand how he had been a dog, but woken up as an insect.

An unknown voice told him to redeem the female insect before him, rekindle his love of life, and prevent the insect race from going extinct in the future.

A rebel commander whose wings had been torn off after his subordinates betrayed him: "Get away from me, vile male insect..."

The puppy didn't get it. The puppy decided to work out: Wer! Come play with me!

After the puppy spent every day dragging the female insect out for runs, training, and mech battles...

The commander, who hadn't slept through the night in half a month: "...Suspend the plan. Somebody come help me raise this dog."

World Two

Mimi was the campus's senior cat. One day, a stranger kidnapped him and took him to an unfamiliar world.

The people there were all strange. Even when they were injured and bleeding, they didn't know how to get treated. They didn't respectfully offer tribute when they saw a cat, either. They even tried to catch cats.

An unfamiliar voice told him to go save the last hope of the apocalypse. Hmph! Cats don't do that.

But this person cooked for him and could scratch under his chin, so Mimi would graciously make him a servant.

What? They pushed the person into a horde of zombies? Don't worry, the cat will avenge you!

A corrupted kitty takes the villain's path and leaves the villain nowhere to go.

Someone lost his kitty and searched everywhere. When he finally found him, the cat had become the leader of a survivor base.

World Three

Mickey was a clever little bird, and he quickly accepted that he had transmigrated into a human.

He might have lost his gorgeous feathers, but he had gained a pile of glittering jewels.

An odd voice told him that, as a "princess" captured by a dragon, he needed to break the curse that said "the dragon slayer will become the dragon." First, he had to save himself and return to the kingdom.

The little bird didn't listen. The little bird chose to build a nest here.

The former hero, now a dragon, came back to find someone had taken over his nest: "...I don't dare open my eyes. I hope this is a hallucination."

After several chaotic worlds, the System was astonished to discover that it had the highest mission completion rate?

[Thanks, fluffies!]
