Leaf Four

Leaf Four (四葉) was Delta's older brother and a member of the Clovers, a small personal group under the Garter Corporation.

Appearance
Leaf Four was a young adult Beastkin Wolf male with short black hair with long dog ears. He adorned an assassin outfit and had a scar on his face, marking him as a member of the Clovers.

Personality
Leaf Four seemingly looked like a vicious assassin at first. However, when backed into a corner, he would reveal his true, cowardly personality and desperately beg for mercy. This sheer cowardice was an oddity amongst Beastkin, who would be more than happy to die fighting till to the death.

In his final mission as an assassin, Leaf Four was envious of his younger sister who became stronger than him and had the best chance at being the next chieftain of their tribe.

Great Trading Company Conflict
Leaf Four and his men were ordered to attack Mitsugoshi Company's carriage under the guise of bandits. But before commencing, they were attacked by assailants resulting in all of their deaths except him. Leaf Four recognized Delta as his long-lost sister, Sara, and tried appeasing her. He desperately tried to use their familial connection to bargain for mercy and he suggested her to become a concubine for the "Legendary Wolf" Gettan, but this only sealed his fate as this moment of weakness was considered a taboo among their tribe. As his efforts to save himself didn't work, Delta executed him without hesitation.

Sarah
In the past, Leaf Four was envious of his younger sister's strength. Upon reuniting years later when she ambushed his squad, he would bargain for his life by having her reinstated into their tribe, though it was an empty promise. However, Sarah became enraged by his cowardice and killed him, stating that she does not need a "weak brother".
