Gekkou Nanase is Takeshi Nanase's younger brother who loves Kurumi Isoshima


Gekkou is a young man of average height and with red eyes. He long black hair that reach to his neck with strands in the front.


Gekkou has a rather complicated personality. At first he seemed to be a rather calm individual who didn't speak a great amount. But after a while he seemed to be usually rather upbeat around others, specifically around his brother and Kurumi, and seems to actually be rather sociable. 

But underneath all that is a rather evil individual. Gekkou's attraction towards Kurumi can be called obsessive. This obsession lead him to being highly possessive of her and jealous towards his brother, to the point of hatred. He also appears to care little for peoples lives, to the point where he hurts others with no remorse, even his own brother.


Gekkou was born approximately a year after Takeshi. Not much is known about his early life other than he did kendo with his brother, and at some point met and fell in love with Kurumi Isoshima.

Sometime during middle school he learned, though didn't believe, that Takeshi and Kurumi began dating. However, after realizing that they were dating, not knowing it was a fake relationship, he suspected Takeshi was taking advantage of her phobia. Thus, conflict ensured between the two. Immediately after this, Takeshi accidentally pushes Gekkou while trying to stop him, gets hit by a car. However, Gekkou sees this as something done on purpose. This apparently caused lasting damage to Gekkou's left leg, causing him to quit kendo. After that incident, Gekkou and Takeshi have had a distant relationship, while Gekkou harbors hate for Takeshi. It later turns out that their mother was responsible for arranging the assassination of her own son Gekkou. The mother did this only to avoid Gekkou from becoming like Kazuma, as she foresaw the potential of Gekkou becoming like him.


Gekkou in the beginning didn't play much of a role in the plot, besides being a key factor to Takeshi's inner dilemmas. But eventually he met and was trained by Washizu Kippei in the use of magic, and joined Ghost Trailer because of his trainer and to fight his brother. During the start of the main characters second year, Gekkou appeared before Takeshi and Kurumi at the entrance ceremony, shocking both of them. After a few days of school, Gekkou appears to want to, and does, make up with Takeshi, upon which the brothers seemed to be back to the way they were before the accident. 

He then was one of the people who saw the awakening of the leader of Ghost Trailer, Kazuma Ryuusenji. After which he participated in the assault on Wizard Brace by Ghost Trailer and Ancient Pendragon, during which he attacked Makoto Hitouji
