Monster Hunter Frontier is a particularly popular Japanese MMORPG that seems to inspire quite a lot of cosplays from Asian cosplayers. Interestingly enough, it also spawns a particularly high number of nsfw ero cosplays as well! Case in point, well known Japanese ero cosplayer NonSummerJack tackles the sensuous Kirin armor for this particular less than dressed cosplay outing.
The Monster Hunter franchise is a series of fantasy video games that started with the game Monster Hunter for PlayStation 2. The series is developed and published by Capcom. As the title suggests, the player takes the role of a hunter in a fantasy environment and completes quests by hunting out specific kinds of monsters to kill or capture. The series has branched out into PlayStation Portable games as well as a massively multiplayer online role-playing game (MMORPG).
The MMORPG Monster Hunter Frontier is available on both the Windows (PC) and the XBOX 360 (Console), though it region restricts itself in order to maintain the best playing experience on a localized basis. The game is presently available for play (and immensely popular just by the way) in Japan, Taiwan and Korea.
