suguru as a fallen angel makes sm sense to me . it just clicks. because, angels, are created perfect. they cannot do wrong , they cannot sin, they do not question. they are crafted by the hand of god from the purest light. not clay as humans and the beasts of the earth are. angels do not bend. they do not break.
and suguru is an angel but he isn't free of sin. he's made of light but there is evil that consumes him. he questions and thinks and ponders and second guesses. he is capable of fault and in what should be the divine perfection of angels, he has cracks and fractures and half healed wounds . suguru does not bend. does not bend but he'll break. all at once, he'll collapse helplessly in a heap
