Art-7- basic. Nothing extraordinary but not "bad" either. I do appreciate how the viewer can easily distinguish the 13 brothers from each other. Usually anime boys all look the same in my opinion.
Sound-9 did well with conveying emotions of the characters. I was able to have this on while working and it did not require much undivided attention since I had headphones in. Audio/dialog is good.
Character-3. The personalities of the brothers were diverse from each other. The main character, (the girl) repeats herself throughout the entire series so this is why the ending is predictable. Her character is the typical sweet/caring/too nice, etc girl. Pretty ordinary.
Enjoyment-3. Did not really enjoy the storyline. It is possible to enjoy an anime even if it has an unfavorable outcome; however, in this case, I feel like it was a waste of time.
Overall-3. Don't waste your time watching this. Do not recommend.
