This anime looks like another RPG theme but there are few things that it attracts attention. I'l write it very shotly with "Cons and Pros" since it's not much you can talk about. So here we go
THE GOOD:
+Art: It is the best thing you can expect from this anime Towns, forest, jungle, ruins are GREAT it's great rarely you will see that kind of quality, Great backgrounds sometimes i even stopped to take a screen shot for my wallpaper and overall it's really good.
+Animation: is good not much i can say about it movement is decent ofc there are expections where it looked like creap but it stands out in the fight scenes.
+Fight scenes: the second best thing, they are very meaning full, it somewhat fits the plot line where a small fight is something huge and you are risking of dying, at this point you start to doubt this is some another RPG theme anime and think about that this is real fight we are looking at.
+Music: Last memorable thing is music, it serves as a good background music forgeting about loneliness, giving new athmosphere and serving as emotions for characters ( what they feel like ) "example" acoustic music can be played after battle for relief.
THE BAD:
-Story line: Man i don't know where to begin is there even a story ? No there isn't. There is ofc small plot line, Characters wake up witout they're momory in this new word and thats it. Yes, thats it, characters simply don't care. You will pretty much will be watching for fight scenes and try to look for interesting/Funny moments when chracters are in the middle of the conversation.
-Characters: Talking about characters they are bland cliche somewhat. There are expections =at the beggining there are 4 characters that you will be interested in but it fades away.
-Enjoyment: because it lacks what it really needs Characters and Plotline this goes in bin of *another boring anime*, if you combine this anime art, animation, sound & Music with some RPG themed anime that has good or decent storyline or plotline *atleast, this will become interesting.
THE personall preference:
+/- OP and Ending are not good at hyping it all up or atleast showing interest, i always skipped it.
+/- some episodes are good some are bland. First episodes are really interesting but that interest fades at the last episodes, goes for personall preferences again.
+/- Ending & Continuation: Ending sucks it endend on boring note, absolutelly no interest for future of this anime not interested in manga or what will happen next in it. I don't know maybe 12 episodes isn't that much, to tell the full tale or explain but it but meh, manga readers won again. But i won too, i'm not interested in this crap.
