Sacrifice (1) 

'If you guys ever think I will let you touch even a hair strand of the people who live here, then you are dead wrong!' the Rune on her back shone with even more intensity as she thought that. 

'No matter if I need to sacrifice my entire body for their sake, no matter if I will need to sacrifice my friends' body for that... You can make it as much painful as you want, but I won't back away.

'I have nothing to lose by paying for my sins. On the contrary, if I can take a single step into heaven after this, just to say hello to my friends, then that's worth it!'

Hera felt her back burning. It looked like someone pressed a hot iron on her skin. She was sweating all over her body, but as soon as the sweat came out, it turned into vapor. 

Her breath was harsh due to her fever, she was gritting her teeth to endure the pain. Moreover, her blood was rushing, boiling inside her veins.
