Can you guess the anime by a single quote?

'Onii-Chan!!'

'We're not gods. We're only humans. We can't even save one little girl, so what good are we then?'

'If today is the worst day ever, then tomorrow has to be better.'

'Do not allow yourself to be blinded by fear or anger. Everything is only as it is.'

'I'm proud of my heart. It's been played, stabbed, cheated, burned and broken but somehow it still works.'

'I can't lose weight; I don't know how to deal with being any skinnier than I already am.'

'Oh, have I not told you how digestively talented I am?'

'People die when they are killed.' :D
