Akiba's Trip: Undead & Undressed

Akiba's Trip: Undead & Undressed is an unabashed celebration of fandom and a love letter to otaku everywhere. It's also a game where you run around Akihabara ripping the clothes off of vampires to expose them to the sun.

The game's ludicrous premise is mostly an excuse for its novel gameplay, but the emotional core comes from its cast and their relationships. These people care about the properties they're fans of, but they care about each other and their home even more. As thin as the story is, it's hard not to be drawn in by the characters.

Waifu Tier
The best of the best. Only one character may be in this tier for a given work or medium. This character... is Mai Waifu.

Harem Tier
The characters who, while not quite waifu material, rise above the rest.

Imouto Tier
From the Japanese for "little sister", characters at this tier are not love interests in the romantic or sexual sense, but are characters that make you want to protect and nurture them.
