Pokémon Pocket Monsters
Anakubo's most famous work is the Pokémon gag manga, Pokémon Pocket Monsters. It was one of the first ever Pokémon manga and remains one of the longest running Pokémon manga to date. It was serialized in CoroCoro from when it was first created. The manga is about the adventures of a young boy named Red and his rude Clefairy. After fourteen volumes, the original series ended, but the adventures of the main characters continued in Pokémon Ruby-Sapphire (which takes place in Hoenn), Pocket Monsters DP (which takes place in Sinnoh), Pocket Monsters HGSS (in which the main characters return to Johto), Pocket Monsters BW (which takes place in Unova), and Pocket Monsters XY (which takes place in Kalos).
Though Pocket Monsters was a success, it was briefly taken off the shelves due to nudity in the second chapter of volume one. There was also some nudity in volume two.
