It's an endurance danmaku

Be as calm as possible and keep it burning for as long as possible

..... Not the sparklers

But anyway, why are there so many sparklers?

For insurance

Fireworks display...?

Because you youkai guys didn't get together for the fireworks display at all

Right

And I thought you were saving it to have fireworks with me

......There's no way such a thing could happen

Ah

Reimu's dropped
