Kei Akashi is a supposed "educational consultant" sent to Kokatsu Academy. He is the fourth main target of the Phantom Thieves of Desire, emotionally manipulating Kumi Katayama to force out the group and discover their identity for his superior. Akashi appears initially to be a mild-mannered, compassionate, friendly, reasonable, caring, sympathetic, humble and kind man that wishes to help his students succeed. However, it is shown that his true nature is a very callous, unsympathetic, calculating and manipulative one, showing this attitude towards those he can make use of and exploit their vulnerabilities. He shows no care for the well-being of those he hurts, latching onto them and manipulating them for all that they are worth.  Akashi is extremely vengeful and will relentlessly target those who wronged him. He believes in a "strong eat the weak" mindset and that those who are strong have the right to exploit the weak to achieve their goals.

Voice Description: Medium male vocal range. For a lack of better terms, he's slimy. Extremely manipulative and intent on carrying out his objectives. Shares no feelings for his own targets or what may happen to them.
