All in all a rather enjoyable addition to the story.
Metatron's first step towards romance made me cry a little and chuckle a little. I loved how vulnerable she was, how lonely she is...
Sam being awkward was very cute and the lewd scene was very sexy. I loved the variety of expressions she has and the outfits. Also I noticed the scars on her arms, proof that she has earned her place as a warrior.
Honestly you'd be surprised how much art I have seen depicting warriors that seem terrified of the idea of letting the character have scars!
The additions to Ashley and Sarah were both fairly small but I appreciated them nonetheless. I never noticed before but it turns out Ashley is a great friend, so supportive!
Sarah on the other hand continues to be the best girl.
The Additions to Celica's story just built further on her personality and the connection she and Astaroth share.
