Akane has a huge crush on Aoi, often letting his affection towards her overwhelm his sense of reason. What with them being childhood friends, Akane is extremely protective of her and would do anything to preserve her safety and well-being. He also doesn't appear to have any interest in anything or anyone other than her, and thus often acts cynical and sarcastic towards mostly anyone who isn't Aoi.

In every other non-Aoi aspect of his life, Akane is a reliable and hardworking student with a professional attitude. He is noted to excel in sports and studies and is currently the Vice President of the student council.

Akane bears deep hatred towards Supernaturals, believing that they do not know the inherent value of human life. He told Teru that he wished to continue the normal life he has led until now, despite having become one of the Clock Keepers.

In Chapter 69, Akane revealed Aoi's intentions in her desire to assist No.6; he says he had always known her genuine side ever since they were kids. Despite the revelation, he continues to love her, even going forth lying about hating her. The part he despises the most, however, was the part where she continued keeping to herself and putting on a cheerful act around others.
