I fail to see why both Chiyuri and the Captain can't be badasses together.
Or that too~
More thoughts on Stage 4-6 and Extra (based on replays):
Stage 4's theme is somewhat hollow-sounding, probably to keep the 'ghostly' theme of the stage. Nothing noticeable happened until Captain Murasa Minamitu enters the stage, and holy, was her theme bad-ass. Once again, ZUN didn't disappoint, though her last spellcard was a bit lackluster compared to her All-Directional Anchor Danmaku, in terms of flashiness.
Stage 5 was... a bit boring. Toramaru was spamming lasers everywhere and somewhat copied Patchy's Non-Directional Laser in one of her spellcards. Her theme sounds intimidating, though; she also holds Nazrin's lantern-thing.
Stage 6 was epicness (even though that's not a word) at its best. The heartbeats were saying 'something is coming' and the atmosphere of the stage was really serious, overall, due to the silence 'cuts' in the music. Byakuren Hiziri was, as Drake said, very Shinki-tastic with the 'wings', lasers, and bullet patterns. She has a magic circle below her feet in her cut-ins, further strengthening her Magician status, and a pretty nice touch.
Definitely an impressive stage.
Extra Stage looks like fun. Stage's theme was nice, though I feel that the pauses on the music were unnecessary. There were laughters in the stage, probably from Kogasa as a sign of playfulness. Nue Houjuu have a very gothic lolita-ish theme; perhaps ZUN tried to invoke the U.N. Owen Was Her? feeling, which did work to an extent. The beginning of the theme reminds me of 'Raging Inferno' from Luminous Arc 2. I could say that this Extra resembles TEoSD the most due to the above reasons. Also, this girl's controlling the freakin' UFOs, and the Raining Wing-Lasers looks awesome.
UFO's looking pretty great; looking forward to play it, myself.
