[Draugur]

Spoiler for walls of text:

In the VN, since like I said, everyone came right from school and never went home the whole time, they obviously didn't have their weapons (except Shion and her ever-ready stun gun), but I liked the anime's change that they left briefly to pick up 'something to fight with' (though Satoshi's bat should have been in the school locker, I won't think too hard on Keiichi getting it quickly, in the middle of the night, when there were probably troops 'readying' the school already :P ). It made things seem a bit more iconic, having Keiichi swinging a bat and Rena with her cleaver, than just teenagers taking out trained professionals with punches and kicks as in the VN.

Spoiler:

The manga also shows them fighting without weapons, and I don't really like it because it looks weak and not at all convincing when they take them out by punches.

Spoiler:

I wish everyone else was killed the same as the VN, though. That is, it's very weird that Takano would only tie up Shion, Satoko and Rika, but put them near the other dead bodies in the VN they didn't run very far from where Keiichi fell, if I recall, but in the anime they're chased through the woods a bit more and...Takano still moved Mion and Rena's bodies closeby? It's silly.

Spoiler:

I thought the Yamainu collected them because they would have to do so anyway, but it's still not realistic.
