what's with the blood?

a reference of how she dies in the anime.

I recall her dying, I don't recall her dying via ass explosion.

it looks like she sat down really really hard

She jump off a roof or something? I don't mind spoilers.

Chestburster.

there is an earthquake and she is one of the victims, she then dies in an messy combination of dirty bandages and blood in her bed. by the side of the boy she always loved.

yeah, Saikano is that chessy. xD
