Apito

Apito (アピト) is an insect Monster that has been found, rescued and subsequently named by Rimuru in the Great Jura Forest.

Appearance
Apito at first had the appearance of an extremely large bee. Later she gained a humanoid form.

Species
Apito happens to be an Army Bee, a queen to be exact, one of the most dangerous species of insect based monsters. They are classed as Special A because they fly at supersonic speeds, can both locate and follow the slightest movements of any being in their vicinity, possess wicked sharp claws and deadly poison. They are also incredibly aggressive and come in swarms.

In the Western Countries when an Army Bee is spotted (and the witness manages to escape with their lives to tell about it) the entire alliance is mobilized, they summon the strongest Paladins of the Western's Holy Church to carefully deal with the threat, placing an anti-magic barrier and still many elites lose their lives in the attempt. In the case where the colony has a queen, the disaster level of the swarm jumps to Special S, because the queen coordinates the exact movements of her subordinates via thought communication and the colony reproduces faster.

These bees also produce the famous honey Rimuru Tempest enjoys to the point of declaring that Apito's production of it is the most important to him, her value as a soldier coming second.

Demon Lord Attacks Arc
While strolling through the Great Jura Forest, Rimuru walked into Apito and Zegion, with the two of them heavily injured. At first Zegion didn't want Rimuru coming any closer, but Rimuru managed to convince them to let him help them. The two end up being rescued by Rimuru when he shared some of his Slime flesh and also named them.

Apito then started her honey gathering duty for Rimuru.

The Octagram Soars Brightly Arc
Apito and Zegion were still in the insect form, but they managed to become much stronger than before.

Zegion
He and Apito consider themselves siblings, having been rescued and named at the same time as well having Rimuru's flesh in their bodies made them inseparable (they are currently the only two subordinates he shared his own flesh with, thus his soul connection with them is wider than any others except for Veldora). At first, they stayed at Rimuru City harvesting honey and training in their free time, then Rimuru assigned them to guard the Treant's Village.

While Apito works on her honey production, Zegion is often seen helping her out, or her helping him train nearby.

Kumara
They have a rivalry bordering on aggressive, purposely making comments towards the other in their face to annoy each other. Despite this, they respect the other and will present a united front to their enemies.

Rimuru Tempest
As their savior and powerful leader Apito sees the king of Tempest as a god given flesh, while not as obvious about her faith as Zegion she still believes there is nothing Rimuru can't do.

Milim Nava
When they first met the Demon Lord both siblings had contented themselves with a peaceful and happy life, this changed when Milim terrorized them into giving her the honey they were harvesting. Although not seriously hurt, the scare was enough to motivate them into becoming stronger.

Ramiris
As the creator of the Labyrinth and someone standing on equal footing to Rimuru, Apito's respect for the Fairy Queen is palpable. She will follow Ramiris' directives unquestionably as long as they don't go against Rimuru's wishes.
