メディオス

Medios is an attractive pale-skinned woman with hip-length dark red hair that is tied up in a ponytail with chest-length bangs covering the right side of her face while the tips of her hair are styled in curls, light-purple eyes and she has a very voluptuous body that can seduce any man. This is seen when Diablo stared at her body and blushed.

キイラ・L・グリーンウッド

Keera was very kind to Shera that he even wanted to take care of her he, right in front of Diablo. He was generous, kind, nurtured his subordinates and his sister, and threatens all-out war over the smallest slight, real or imagined. He was incredibly racist against every other race. He spoke in polite terms, but his tone was condescending, arrogant and petty. When he had Shera at his mercy, he loves to boast about how their elder brother "died in a hunting accident" thus, in his mind, making Shera his slave instead. He was convinced that he's the smartest and mightiest being in the world and will happily boast it to anyone and everyone. When he was directly challenged, however, he was very quick to run and hide behind someone or something, even summoning the Force Hydra at the first opportunity, and yelling at it to attack Diablo, despite clearly not being able to control it in any way. When Diablo, Rem and Alicia called him out on siccing a slime on Shera, before intending to rape her, he retorted that using the slime that way is foreplay and he believed it. When Diablo used his authority as Shera's "master" to compel Shera to profess how she truly feels, and Shera goes on to condemn the act, Keera loses what little sanity he had. His behavior as he was called out on his crimes is precisely like a spoiled child getting his toys taken away when his parents have had enough. He called everyone he comes across "stupid," especially when they are of another race, don't agree with his mindset, or both. He genuinely believed the world revolved around him. When he realized it didn't, thanks to Diablo completely crushing his defenses, taking Shera back, overcoming her brainwashing, and Alicia repeatedly pointing out that Keera's actions are violations of international law... He not only vastly overestimates his abilities, but looks down on everyone, and thinks they're idiots for not agreeing with his agenda. He called his father "feeble" for being reluctant to lead an invas
