Just in case people don't know, the finale of the manga is very different from the novel.

Spoiler for novel finale:

I'm gonna spoil part of the end of the story here beware!!

Spoiler:

In the novel the youth hostel is owned by the maternal grandparents of Takabayashi (the one who died of a heart attack). The grandmother goes insane after probably learning something about the death of her grandson and goes on a rampage. She first kills her husband, sets the kitchen on fire and then starts a killing spree through the building.
She is revealed to the reader when Kôichi returns to the hostel after checking on Kazami. There he sees Akazawa screaming in her room, a figure approaching from behind and then her falling down the balcony with stabwounds over her body. Then Kôichi tries to run away from killer-grandma and is saved by Chibiki.

So, no fight between Akazawa and Mei and no magical lighting making the gas tanks explode...
