First one is of Imperishable Night's final boss, Kaguya Houraisan. I cleared that with Reimu and Yukari. Whiles the next half - I'm not that pleased with it - is of Mountain of Faith's Kanako Yasaka with Marisa B. I kinda used the glitch once or twice when I had to.
Oh yeah, notice the translation Kaguya's fight. when she says 'odd guests like you are most welcome' and Reimu says 'SHOT guests?'
What it means there is that 'tama' (in Japanese) means 'odd' or 'shot'. This was translated by patch. Just thought I'd point that out ^^
