Yugi Amane (Hanako-Kun)

Being the seventh school mystery and the leader of the Seven Mysteries, Hanako maintains the balance in the relationship between humans and supernaturals of the school, and is often seen helping others around and protecting the school. Hanako is cheerful, outgoing, and likes having fun. As a ghost, he is rather mischievous, then he enjoys teasing others and can be very playful and pranky. Despite his youthful persona, Yako and Tsuchigomori respect him and follow his orders as fellow school mysteries. He can become very serious at times, but at other times he appears very flippant. Hanako is also a bit sadistic at times, as shown when he happily threatened to turn Yako into fox udon (he often threatens others with his kitchen knife). Yashiro Nene describes him as someone who is difficult to understand.

Hanako's personality is similar to that of when he was human, except for the fact that he was very passionate and knowledgeable about astronomy and dreamed of being an astronaut. However, he no longer talks about the subject. Furthermore, when he was alive at least in the school, he seemed more closed and shy. He doesn't like talking about or being reminded of his past due to the negative associations.

When upset, Hanako tends to find isolated locations such as the rooftop. In the presence of others, he often smiles to mask negative emotions. Though he tends to smile at inappropriate times, seeming not caring about what is happening around him, his actions prove otherwise. He rarely talks about himself and it is hinted that this is because he fears of revealing his past to others. This self-isolation and bottling of his emotions leads to his tendency to make decisions without consulting others. Hanako rarely asks for advice or help when it comes to solving problems, and as such he can be rather callous. He often assumes he has the best answer to a problem and will go through with his solution even if it may come at a very high cost to either himself or the person he is attempting to help. He will even lie to further his goals, which makes him seem rather duplicitous at times.

Hanako has expressed a great deal of affection and concern for other individuals, especially his human companions, despite denying so. He is shown to deeply care about his friends and be especially kind to them, as seen when he constantly helps Yashiro Nene and sincerely apologized when he hurt her feelings.[3] When Nene is tired, he cheers her up with a kiss, and on one occasion he searched all around the school to find the Mokke's hidden trinkets, which included Minamoto Kou's earring. He also opens up considerably with their company even though little is known about him, confessing that his favorite dessert is donuts, which surprised even Tsuchigomori. Despite his affection for his friends and general regard for human life, Hanako can also be apathetic towards those he does not value highly. He is willing to sacrifice or harm others if it would be beneficial to his close friends, particularly Nene, based solely on the fact that he likes her more than those he does not know.
