User blog comment:AquilaeAltair/OnS Theories (5S) - Third Theory - Rigr’s weapon: An incomplete seraph/@comment-36009152-20190820011723

Seraphs being well hidden within plain sight is becoming increasingly likely. There has also since been the revelation of past activities such as Sika Madu possessing seraph wings since unrecorded history so yes could be lurking anywhere, oh and anytime as well!

Rigr seems to have gone beyond what Shikama Doji delved into with the first vaguely making out but not completely familiar with the apocalyptic like beasts Rigr could summon.

On the essence modifications to call them that, yes they are impressive the lengths he would go to, but on those was also thinking about how there is a realistic chance for Mika to change from a vampire if he still really wanted that.

In any case, true Saito has been busy making himself with unique powers. He is like the first in that he can, presumably imitate demon, vampire and seraph powers, but remains something else particularly with these life sapping, lethal chains.

Good observation that what else uses chains, why seraphs of course! Then his pose before summoning those creatures, yes think it’s clear we are looking at Saito having acquired himself seraph powers and also displaying possibly their full power as he can use them, wow!
