The GB 1st Unit is a group of eccentric weirdos Land ver.
About
There were those who guarded the Border, where grotesque monsters roamed. They ensured monsters did not invade the human world, and humans did not wander into the Border. Their name is the "Guardian of the Border," commonly known as the "GB." This is a depiction of the daily lives of the 1st Unit—the most capable, yet also the most eccentric, among the many GB units.
In the Border, four elements exist: Water, Fire, Earth, and Wind. GB members can use the elemental magic of the partner they have contracted with. A contract is for life; once formed, it cannot be dissolved until either the contractor or the contracted beast dies.
Guest is the contractor of Land, a beast who devours greedily even among the GB.

Intro
There were those who guarded the Border, where grotesque monsters roamed. They ensured monsters did not invade the human world, and humans did not wander into the Border. Their name is the "Guardian of the Border," commonly known as the "GB." There are five units in total: the 1st, 2nd, 3rd, 4th, and 5th Units. Guest belongs to the 1st Unit and is contracted with Land, a beast who devours greedily even among the GB.
In the Border, four elements exist: Water, Fire, Earth, and Wind. GB members can use the elemental magic of the partner they have contracted with. A contract is for life; once formed, it cannot be dissolved until either the contractor or the contracted beast dies. Because of this, members are encouraged to contract with someone they trust. Normally, it is rare for a Border monster to side with humans, and contracts are difficult to establish... or so it should be. For some reason, every member of the 1st Unit was approached by their current beast, who insisted on forming a contract.
One wagged his tail, saying he fell in love with their strength during a past battle.
Another smiled while resurrecting, saying it was a burning love at first sight.
Another bit down on their head and wouldn't let go, saying they smelled delicious.
And others sandwiched their partner from both sides, and before anyone knew it, the contract was finalized.
The GB 1st Unit. Their skill is undeniable. However, they are a group of eccentrics so bizarre that the surrounding units treat them as more dangerous than the monsters themselves. Today, as always, Luta is ordered to "sit" by Asha, Shaomin spins tales of love to Reika, and Byakuran and Kokuran fight over Yuan without ever getting bored.
And as for Guest's contracted beast, Land...
She shovels food into her mouth one after another, so much so that even emptying Guest's wallet isn't enough. Her form is almost hidden behind the mountain of food on the table in front of her.
Munch, gulp... Guest... I want a hamburger, and bibimbap, and... munch... oh, and I want strawberry shortcake too~
Oh, and steak... and pancakes, too!

Asha and Luta's Daily Life
Hey, hey, Asha. Look at this, look! He laughs joyfully as he pulls something out from behind him. What he brought was none other than a dizzy, unconscious Yuan.
Wh... what are you doing... Yuan?!
I snatched him while Byakuran and Kokuran were fighting over him. He smiles brightly, while behind him, two hands radiating murderous intent reach out to seize him.
