The letter from Balberith to Issey:

""I am very interested in Oppai Dragon, every time I see it, I feel it in my heart. I have a mother but no father. Can you be my chichi (father) if you can?" Grim Reaper. Issei is touched by the letter, Ravel says though his position is complicated, if Oppai Dragon can save a child thats a good thing. Issei immediate writes a reply in his spare time. "

For all his immense Power he is still a Child in a way...feels a little sad
