Since I feel some of the types I listed on the previous list were incorrect, I've decided to retype the characters from Nabari no Ou after further analysis:
Miharu Rokujo: INTP 5w6 (while apathetic and detached from much of reality, Miharu appears to assess his environment objectively and often sees random connections among the symbols surrounding him, which leads to his constantly trying to obtain that one logical truth and answer for everything that been enforced upon him, in much the same way as an INTP. Beneath his indifferent exterior, he is rather reflective and contemplative, continuously analyzing his inner self and wondering deep down where the root of all his apathy comes from, while at the same time having an extremely underdeveloped Fe that prevents his caring for or empathizing with the people around him. )
Yoite: ISFP 6w5 (While externally seeming just as apathetic as Miharu, Yoite internalizes much of emotions and is constantly questioning his sense of purpose and identity, feeling dissociated from himself due to the circumstances of his past, and therefore finding the meaning to his existence to be uncertain. Likewise though, he looks to his
Raimei Shimizu: ESFJ 2w3 (although rather extraverted and concerned with the emotions of others, Raimei remains very focused on the past and struggles to abandon previous grudges, hence her initial desire to avenge her clan's passing by defeating her seemingly relentless brother. Nonetheless, Raimei is practical and present-oriented, meticulously planning her training sessions and serving as a caretaker of sorts where it concerns the group's feelings, particularly Miharu's).
Koichi Aizawa: ENFJ 9w1 (Koichi possesses the outwardly energetic, accessible exterior of most ENFJs, but simultaneously knows how to alternate between playfulness and solemnness, depending on the current circumstance, and seems continuously focused on fulfilling one particular goal. He also has an underlying inclination toward the philosophical that causes him to occasionally question his purpose and the positive meaning in being immortal).
Gau Meguro: ENFP 7w6
Hanabusa Seki: ISFJ 2w1 (stereotypical maternal figure and symbol of femininity who serves as a nurturer of sorts toward Tobari and the rest of the group, when circumstances call for it).
Raikou Shimizu: INFJ 1w9 (while outwardly easygoing, mild-mannered, and approachable, Raikou often detaches from his outward warmth to reflect on things from a colder objective stance due to his tertiary Ti and often remains resolute when attempting to fulfill one particular purpose).
Tobari Durandal Kumohira: ESFP perhaps (he's excitable and a bit scatterbrained, which occasionally makes him a questionable leader for the group).
