Made in 1994,Blue Seed is (loosely) based on the Izumo cycle of Japanese mythology and the tale of the god Susanoo and the eight-headed monster Yamata noOrochi. The original manga was written by Yuzo Takada and was made into a 26 episode anime series.

Momiji Fujimiya, a normal middle school girl, is one day stopped on her way to school by a cat-eyed man with greenish hair and magatama beads (read: blue seeds) who calls her "Kushinada" and then tries to kill her. Momiji is saved by the sudden appearance of two government officials, one of whom shoots the man in the arm and sends him fleeing.

Momiji is intrigued as to why she was referred to as "Kushinada". She discovers that "Kushinada" refers to an ancient princess whose blood holds the power to stop the ancient monsters known as Aragami by sending them to an eternal sleep. Momiji dismisses the idea that she could be such a person, despite the fact she lives with her mother and grandmother in a shrine in Izumo. However, she soon changes her mind after vines begin to appear from every crack and opening attempting to capture her as they whisper "Kushinada".

Momiji tries to escape, not knowing that the vines are being employed by a powerful Aragami known as Orochi. Fortunately, she is saved by the man with the magatamas embedded into his hands, who introduces himself as Mamoru Kusanagi. He confronts Orochi using Momiji as bait. The plan fails and the government officials appear again. They reveal themselves to be members of the Terrestrial Administration Center (TAC for short), and manage to subdue Orochi. However, with the last of its strength, it makes a final attempt on Kusanagi.

Momiji saves Kusanagi by taking Orochi's blow. Impaled by the Aragami, instead of dying, she is instead fused with the magatama, more specifically identified as a mitama, which gives Momiji the ability to sense the presence of other Aragami. The TAC agents explain that they are an organization dedicated to defeating the Aragami, who seek to destroy humanity. The current Kushinada, Momiji, must aid them because the other Kushinada, Momiji's twin sister, is thought to be dead. Momiji, wishing to discover more about the twin sister she never knew and also to fulfill her destiny, agrees to join the TAC under the protection of Kusanagi, who wishes to destroy his former masters, the Aragami.

The story becomes increasingly complex with the appearance of Murakumo, a man with eight mitamas who kills any Aragami he comes across for his own personal reasons. Kusanagi repeatedly attempts to kill Murakumo. Then Momiji's twin Kaede reappears along with a strange energy field in Tokyo, and Murakumo and Kaede's plans soon become clear - they intend to resurrect the god Susano-oh and purify the world of humanity's influences, with Kaede acting as the leader of the movement.

There is also a three episodeOVA,Blue Seed Beyond, which takes placetwo years after the end of the TV series. It concerns what seems to be a resurgence of aragami (actually created via biotechnology), and introduces a new character, Valencia Tachibana. Like Kusanagi, she was implanted with a mitama without turning into a full aragami.

Has nothing to do with the "sour, yet refreshing" spice from theLost in Blue games.

• Action Girl: Koume and Sakura.
  • Also Valencia in theOVA.
• Adaptation Expansion: Whereas many animeOvertook the Manga, the manga for Blue Seed was only two volumes, so the anime added some episodesfocusing on the characters. The fact that there were also Aragami attacks kept these from being outrightFiller.
• Alien Blood: Aragami and half-aragami have green blood.
• Anticlimax: In theOVA,theBig Bad goes down with a few gunshots, despite looking a lot tougher than that.
• Apocalypse Maiden:Kaede, after herFace Heel Turn.
• Badass Normal: Sawaguchi Koume. Her philosophy can be boiled down to "Bigger Gun."
• Barbie Doll Anatomy: Averted as part of theOVA's fanservice.
• Barrier Maiden: Kaede and Momiji.
• Big Ol' Eyebrows: Used... interestingly. Rather than give Kusanagi bushy eyebrows, he ends up withfour normalish ones. This isLampshaded in anOmake.
• Blade Below the Shoulder
• Bodyguard Crush: Momiji on Kusanagi.
• Book Ends: The first and final omakes end with the same scene: Momiji blasting the heck out of Kusanagi and Kunikida.
• Brick Joke: The first omake has Kunikida buying sexy pictures of the TAC girls from Kusanagi, with the ones of Momiji still being developed. Then Momiji shoots them with a machine gun. In the thirteenth and final omake, those photos are finally developed and seen just before Momiji again shoots them with a machine gun.
• Bring My Red Jacket: Kusanagi, though the blood thing doesn't fit so much, since his isgreen.
• Broken Bird:Kaede. She apparently had herFace Heel Turn because the TAC used her abilities but never saw her as a person.
  • Momiji actually called them on out on this in the third episode when they tried to do it to her. That time around, they listened and made her a full-fledged member.
• But Not Too Foreign: Yamazaki Sakura, Japanese but raised in America after her mother died.
• Chivalrous Pervert: Kusanagi
• Clothing Damage
• Comedic Underwear Exposure: Happens with almost monotonous regularity to Momiji.

• Dojikko: Momiji
• Excited Episode Title: All but two titles.
• Evil Twin: Kaede to Momiji.
• Fake American: Sakura again, who will occasionally try to curse in English. "Sohn obe ah beachy!"
• Fan Service: Yaegashi's computer program to predict the weakness of enemies can also be used to figure out what kind of panties Momiji would be wearing that day. She was unamused.
  • And then there isSakura groping Momiji's breasts inBeyond, just to admire how much they'd grown.
    • Valencia provides alotof fanservice all on her own.
  • How many times we've seenMomiji's panties?
• Gag Dub: The monster movie omake, at least in the English version, was a take on old, poorly-dubbed kaiju films.
• Gainaxing: Namely inBeyond.
• Godiva Hair:Sakura's mom.
• Goofy Print Underwear: A running gag with Momiji.
• Gratuitous English: See entry forBut Not Too Foreign, above. The shift in Sakura's pronunciation from "Mommy" (American) back to "Mama" (Japanese--Engrish, but still Japanese) actually marks an important turning point in one episode.
  • AlsoMYSTERIOUS TOKYO! HOOK ME UP FOXY NIGHT GAME!
• Green Aesop
• Hellish Pupils: Kusanagi's are slitted like a cat's; Murakumo's have the whites and the pupils inverted, colorwise, in one form.

• Hot Springs Episode: The thirdOVA episode, in which the team must deal with a bomber and some monkeys.

• Kotono Mitsuishi: Koume's voice actress.
• Limited Wardrobe: OneOmake has Matsudairawondering why Kusanagi always wears the same clothes and if he ever takes them to be cleaned. This is even more amusing when you consider that Kusanagi's trademark red coat tends to get literally torn into small pieces during his transformations, yet in the next episode it is usually seen again, undamaged.
• May-December Romance:Ryoko Takeuchi and Daitetsu Kunikida
• Meaningful Name: Kusanagi Mamoru. Mamoru mean "to protect," and Kusanagi is the holy sword of the Japanese emperors, which apparently once belonged to Susano-o. It means the grass cutting sword (long story). Murakumo, the cloud cluster sword, is another name for the same sword and is the name of another character. He's trying to kill Kusanagi.

• Replacement Goldfish: Momiji's twin sister was no longer available to be used to quell the problem, so the job fell to her.
