Re:Monster

Tomokui Kanata was stabbed and killed with a knife. When he wakes up, he has been reincarnated as a baby goblin in a different world, named Gobrou. Gobrou begins hunting together with the strong Gobkichi who was born at the same time as Gobrou. They start hunting, dividing their roles to catch their prey.

Gobrou, who has ranked up, evolves from a goblin to a hobgoblin. He takes on the role of trainer for other goblins of the same generation and begins training them. When the goblins of the parent generation who had gone away from home return to the cave, they capture human women for breeding purposes, which Gobrou finds hard to accept.

After defeating Red Bear, Gobrou evolved into an Ogre. The captured adventurer girl, the short-haired redhead, and other women began to show affection for Gobrou. Meanwhile, Gobrou, who was tasked with collecting the spirit stones, brought the blood-stained Carbuncle Litana back to the cave.

A messenger from the Elven tribe arrives at the Gobrou cave. They ask for help to fend off adventurers who are after their treasures, but the Gobrou have nothing to gain from this. The Gobrou turn them away once, but a few days later, the elves come again.

With the kobolds now in their ranks, Goburou and his friends capture a human soldier who was targeting the elven shrine maiden. They extract information from him about the human army's invasion and decide to return the elven shrine maiden to the village.

Ogrou, who formed the mercenary group "Para Bellum," accepts a request from the elves to repel the human army. Para bellum members confront the enemy with all their might, not only capturing the four targets they aimed for but also defeating the soldiers mercilessly.

In order to obtain the elixir from the elves, the Imperial Army deployed the Eight Heroes Cavalry Corps, a combat unit consisting of eight individuals blessed by the gods. Realizing the enormity of his own power, Ogrou uses his avatars to scatter the soldiers and confronts one member of the Eight Heroes Cavalry Corps, the hero of the Bug Brave.

The battle concludes after the secret potion is handed over to the Imperial Army. Although Para Bellum suffered casualties, many of its members have evolved as a result of the battle. Additionally, the prisoners of war are released, and those who wish to join Para Bellum are allowed to do so on a provisional basis, but they are dissatisfied with being treated worse than goblins.

Ogrou and others arrive at the Garrison City of Trent, the destination of the girls. Ogrou tells the girls that they have to decide whether they want to stay in the city or continue to work with him. The members of Para Bellum start gathering information in the city, but the townspeople are still frightened by Ogrou's appearance.

Ogrou and his companions are tasked with escorting Princess Rubilia to the royal capital, so they head to the Cluster Mountains, where Jade Eagle, the strongest of the four-winged eagles, lives. However, on the way, the health of the twin chef sisters deteriorates.

The members of Para Bellum arrived at Purgatory, the final stop before the royal capital. Ogrou, who hadn't spoken to the separate task force members for a long time due to childbirth commotion, contacted them.

Finally, the group arrived at the Royal Capital of Oswell. After receiving their reward from Rubilia, Ogrou and the others decide to return to the village. On the other hand, Dhami, feeling pressured by Ogrekichi's growing strength, was troubled by still being only a half-vampire.
