I finally watched episode 1 (raw). It was a LOT better than I was expecting, since the OVA had awkward animation and a boooooooring story. But episode 1 of the TV series was exciting. :D
To my surprise, most of the episode used darker colors and smoother animation than any other shoujo I've ever seen. It has a shoujo story with shonen-style animation (reminded me of Junni Kokki/Twelve Kingdoms). It's so good!!
Here's a brief summary and screencaps by me of episode 1:
Spoiler for episode 1 summary:
(since this was from a raw, it might not be 100% correct, because my japanese is not 100% correct)
While walking with her friends Shimon and Tenma, high school girl Akane suddenly hears a voice calling out to her. In somewhat of a trance from the "voice", she follows it and finds a strange well. A light shoots out of the well and pulls her inside. Tenma and Shimon, trying to hold Akane back from the well's pull, are also sucked into the well.
Akane wakes up to find herself in a dark room at night in an old-fashioned Japanese-style house. She opens the door and finds a girl wearing a kimono. Confused by her new surroundings, she leaves the building, only to find an alarmed-looking man with a sword, mistaking her for a strange tresspasser. Akane sees the sword, screams, and is surrounded in light - transported elsewhere.
After meeting with a mysterious blonde man, Akane roams around the foreign town, wondering where Shimon and Tenma are. She eventually finds Shimon again (who is being tormented because of his blonde hair and blue eyes, which are traits of oni/demons in this world).
The earth around Akane begins to shake, and a violent light comes out of the ground. The swordsman from before (Yorihisa), stabs a vein in the ground and rescues Akane.
Akane is safe for now, but where is she? Where is Tenma? Looks like she'll try to figure these things out next episode... ^^
