The main conflict of Gankutsuou and Birdy 2 revolve around a character and his single-minded berserker-like need for revenge against a group of characters that ruined his life. Also, both are sci-fi that involve some aliens/outer space stuff.
Kagura and Yomi are two girls who have a bond that cannot be broken. While once they fought side by side against the supernatural forces that threaten the planet, fate had something different in store for these star-crossed companions. Yet to understand the present, one must first experience the past – a time before Kagura’s involvement with the Supernatural Disaster Prevention Agency. Always cheery and good-natured to a fault, the young Kagura first meets Yomi when she is invited into her home. Over time, the two battle malicious spirits and grow closer together – but soon, more terrifying foes begin to reveal themselves. A swarm of glowing blue butterflies and a mysterious stone are harbingers of darker things to come, and one thing’s for sure: Kagura and Yomi will never be the same.
When Asaba sneaks into the school at night for a quick swim, he doesn’t expect to see a strange, vacant-minded girl with orbs stuck in her wrists right there with him. Stranger yet is when the police come to take her away... but to his surprise, he sees her the next day at school, a new part of his class! His interest in the girl piques the jealous curiosity of his friend Akiho, but between air raids, military operations and a possible alien invasion on the horizon a love triangle is the least of Asaba’s worries. Will Asaba come to terms that the fate of the world and the fate of the girl he loves are two very different things?
Welcome to a world in which memories can be transferred from body to body; old painful memories can be removed and replaced with new ones, and the poor sell their bodies to the rich to survive. Waking up one day, Kaiba finds himself in a strange place with no memories of his past and a mysterious hole in his chest; the only clue as to his identity is a locket with a picture of a girl hanging from his neck. Armed with this token, Kaiba must now travel across the galaxy to discover who he is and what the girl in the locket means to him; however, his journey will bring him into contact with many people whose lives have been tragically affected by the manipulation of memories. All too soon it becomes clear that something is very wrong with this world…
There's a really cool dynamic introduced when one character jumps directly into another character's memories. Kaiba jumps into all sorts of peoples memories (for superior breadth on that regard), while in Birdy 2, only the titular character's memories get explored (for superior depth), but both are really interesting.
