Marin A Go Go is a series of H-OVAs, but then I found Nonoya made some Doujins about it. The artwork is fucking amazing, the first part by Nonoya, which style I love, specially for those juicy asses; and the second by my God Type.90, in his golden years; the plot is good, still in the quest of the perfect japanese man; the action is fucking hot and inciting as few, including a lot of hardcore sex and hot cosplay in the Type.90 story; and finally the censorShit is minimal. So, overall, this can't be considered a Doujin, but a piece of Paradise itself drawn by two of the greatest artists in the business.
Final Call: This was made to be enjoyed at our heart's content.
