Gekkoh deals with the story of a boy trying to figure out how to deal with his role as the son of a yakuza boss while helping his new-found sister uncover the story of her past. His other problem is the constant struggle with his own consciousness for being sexually attracted to his half-sibling, who tempts him at every opportunity.

At first, Gekkoh does not reveal anything that feels remotely engaging. The story seems cookie-cutter, the characters are flat and the pacing uneven. However, once you skip past the middle (around volume 5), things start looking for the better as more of the story is revealed and the author regains some control over the narrative. You can see the main character develop as a person as a result of his feelings for his sister and the situations he has to go through in order to help her. Later on, some characters revel unusual personality traits and there are even a few jokes thrown in here and there. Expect a few predictable plot twists as well.

The artwork is fair, erring on the side of 'generic' but it gets the job done. Characters could benefit from a more artistic depiction but the environments and some of the background images are done well. The sex scenes are depicted with relative frequency but the author somehow manages to avoid making them feel excessive.

The author uses direction no just to advance the narrative, but also to provide an excuse for depicting erotic parts and sex scenes in the story. While this may decrease the enjoyment for some, fans of the 'ecchi' genre will definitely be satisfied.
