Got some tips for whoever actually wants to see the animations this time around.
First the boss has 3 attacks it cycles through, shadow clones that rush at you, jumping through the air and dropping bombs, launching a white blade beam at you.
Both h animations require you to be in stripped mode which is when yagiri's tits are out. Get attacked and you can see yagiri's scene.
The boss also has a scene this time around, which you can view by holding down while standing in front of the boss while she's stunned. To stun her, you need to use the up + z attack which throws a chakram upwards while the boss uses her jumping through the air attack.
Each second in the h animation uses some of your scroll power, which you can get by attacking the blade beam in the boss' third attack. I suggest just getting your bar to full first in order to see the full animation because otherwise you just get knocked out of the animation
