KO Seiki Beast Sanjuushi

The series is set in the distant future in which the Earth is split in two. The southern hemisphere is placed in another dimension while the inhabitants of the northern hemisphere are able to morph into beast-like humanoids. Eventually the humans of the southern hemisphere, led by Uranus, attack the Beasts. The Three Beasts, Wan Derbard (Wan Dabadadatta) of the Tiger Tribe, Bud Mint (Baado Mint) of the Bird Tribe, and Mei Mer (Mei Mah) of the Mermaid Tribe, are taken prisoner along with Mei Mer's companion Tuttle Millen (Mekka Mannen, also of the Mermaid tribe), but manage to escape thanks to a little girl named Yuuni Charm Password. Together they seek Gaia, which they believe to be a fabulous treasure, but they are pursued by Uranus's minions : V-Darn the vicious mage-knight, V-Sion the warrior woman and Akumako, V-Darn's sadistic imp-like partner.

Kobayashi ga Kawai sugite Tsurai!!

Twins Megumu Kobayashi and Mitsuru Kobayashi attend different schools, one for girls and one for boys. One day, bored with being surrounded by others of their own gender, they decide to swap places with one another. While the deception seems to go unnoticed for some time, things get a bit more complicated when the possibility of romance arises. Kobayashi ga Kawai sugite Tsurai!! begins when a heartfelt confession from Megumu leads to sharing a kiss with the upperclassman Aoi Sanada while disguised as her brother. This leaves Aoi, who was never good with girls to begin with, questioning if he likes guys instead. Likewise, Mitsuru finds the haughty queen of the school, Azusa Tokugawa, in a vulnerable position that leaves her heart racing while in his (her) arms. The two couples are lovey-dovey, but the secret of the twins' switched identities has not been revealed yet...
