Amnesia (stylized as AMNEƧIA) is a Japanese visual novel series by Idea Factory.

They were later combined for a PlayStation Vita release titled "Amnesia Later x Crowd V Edition" in October 2014.

In Amnesia, the male characters that the female character can interact with are based on the symbolic suit symbols from a card deck with the following storylines, commonly known as routes: Heart, Spade, Clover, Diamond and Joker.

Each route is a parallel world where the heroine seeks to understand more about her selected male character.

The premise to the game is that a sprite called Orion accidentally attaches himself to the Heroine, causing her to lose all her memories.

In order for Orion to free himself and return to his own world, the Heroine must regain these memories through interactions with important people and places in her life.

During Otome Party 2012, production of an anime television adaptation was announced with an expected broadcast in 2013.

As the heroine and Orion head home, she is almost run over by a truck, but a mysterious young man with long green hair, named Ukyo, saves her.

At night, walking outside with Shin, she becomes frightened of him and starts running away from him, and accidentally falls off a cliff.

It’s her destiny, after all.” Shin takes the Heroine home from the hospital, and quickly figures out that she has lost her memories.

After briefly hearing Orion’s voice, the heroine talks with Shin about their relationship.

Shin arrives to talk to the Heroine alone in the forest, and pins her to a tree as he explains the accident.

Ikki escorts the Heroine home, where she gets a text message from an unknown person about a "daily report."

She finds a locked diary of hers, and learns from her calendar that she had been planning to regularly meet Ikki in a certain back alley.

Ukyo disappears, and Toma comforts the heroine, offering to let her stay at his home for the night.

The heroine arrives home, picks the lock on her diary, and learns that she loved Toma, and that August 1 was the day she had planned to tell him.

Ukyo talks about their past together and the well at the old shrine nearby, then suddenly crouches in fear mid-sentence.

Anime News Network's Rebecca Silverman gave the first half a C grade overall, commenting "Parts of it are fascinating...while other parts are intensely annoying", and said the show "basically feels like watching someone else play the game.

"[5] Matthew Lee, writing for Twitch Film, opined that Amnesia's "story offers nothing of any interest beyond the burning question of what the hell any of it means.

"[6] Seb Reid of UK Anime Network rated it 4 out of 10 and called it "A show that is best forgotten.

"[7] Silverman gave the second half an overall grade of D, saying that "Ultimately Amnesia ends as it began – fascinating in the same way a loose tooth is, but the payout when you finally get rid of it doesn't feel like enough.
