Gameplay
http://portal.million-arthurs.com/maab/The protagonist, who had come to study abroad under the pretense of cultural exchange, gets dragged into a “space-time distortion” while sightseeing at the ruins of King Arthur and is sent back in time to Britain.
Led by a mysterious fairy, the protagonist pulls out the sword Excalibur and becomes Arthur, but the sightseeing guidebook he was carrying is mistakened for the divine history book known as the “Akashic Records.”
For that reason, those around him mistake him as the “historian who came from the future,” and in order to accumulate “holy blood” and return to his original world, he must participate in a grand martial arts tournament.
The game is similar to Dengeki Bunko Fighting Climax & Nitro+ Blasterz and also star's Lise from Seiken Densetsu 3. The arcade version is using Taito’s NESiCAxLive 2 service.
