The Cross of Guilt

Egregia signorina Messia*, I always see you shouldering that Holy cross on your back. *My dear lady Messiah

...Perchance, are you burdened by some kind of guilt that you've found the need to carry it...?

Yes, it is as you say...

In my past, a dreadful catastrophe happened. Countless children, dying, right before my eyes, yet there was nothing I could do to save them...

That is why, ever since then, I always bring this emergency medical kit with me, wherever I go...

Oh, quindi era uno zaino...? So it was a backpack..?
