Atsushi Nakajima is a member of the armed detective agency with the ability Beast Beneath the Moonlight. The ability gives Atsushi the ability to transform into a white tiger. At first, he did not seem to have much control over the transformation, likely due to the fact or caused by his unawareness of his state as an ability user. After becoming an official member of the Armed Detective Agency and under the influence of All Men Are Equal, he gains more control over his transformations. He has white hair, pale skin, and striking yellow-purple eyes. Standing at 5'7", he has a skinny build. Due to a traumatic past as an abused orphan, Atsushi is often anxious but overtime learns to overcome that and he becomes quite sassy. Despite his past, he is incredibly nice, sweet, and selfless, often prioritizing others over himself. He can also tend to stutter apologies when flustered. He likes to cook, chazuke (a savory Japanese dish made with green tea poured over rice), cats, chameleons, and Yokohama. He dislikes selfish people and people who use their abilities to do others harm
