This seems cool! My main request is that you use a feast stage (Hakurei Shrine at night) and have Demystify Feast (or a remix of it) as the music.
Also, a character hopefully no one suggested yet...
Byaruken
Specials:
Neutral: "Star Maelstrom" Fires a small curving laser to both sides, can combo enemies, peters out eventually
Side: "Lotus Glide" Glides in the air (or on the ground) to the left, if less than 100% does much damage but little knockback, if more than 100% on enemy it does the opposite.
Up: Hijiri "Superhuman" Goes up in a Z-shape, gets a jump at the end, combos and takes enemies with her
Down: "Prayer" Similar to Deep Breathing in Smash 4 on Wii Fit Trainer, time it right and you get a temporary boost in Attack Power and Knockback.
Smashes:
Side: Creates a lotus (similar to Mario's side smash)
Up: Shrouds the area around her with purple bullets (Nirvana's Cloudy Way in Purple)
Down: Creates two lasers that go to each side of Byaruken and bounce off the ground into the sky.
*Couldn't think of aerials or tilts, sorry :V
Final Smash: "Devil's Recitation" Basically a recreation, all bullets deal 3% each, lasers deal lots of damage and knockback.
Side: Creates a lotus (similar to Mario's side smash) that does massive damage.
