So - he's still a murderous stab-fiend.
BUT - I do empathise with him as Eligos has been nothing but kind and loving towards him, even when his own family turned their backs on him. And I'm quite glad that he has a bit more backstory as a result, because people aren't just born evil, and smol Leo is proof of that.
It's such a shame that he's become so blinded in his quest to keep Eligos by his side that he hasn't comprehended what Ritsu is trying to achieve.
I hope that he'll fogive Leo and allow them both to live their lives out together, because lovely fluffiness.
