Started watching it 2 weeks ago when Shinsen began subbing.
It is really good. Sort of reminiscent of Shakugan no Shana, Zombie Loan and Fate/stay Night but darker...bodies turned inside out!?!
Guess I'll give you the gist:
Shin(17) and Jun(13?) return to their hometown to live with their brother Ryo.
Ryo is the police superintendant and he is investigating mysterious illness called the Apathy Syndrome that has befallen people.
Guardians/Persona's do come into to it. But i don't want to ruin it...
Another reason i love this anime is the intro, the song is just great. Reminds me so much of Zombie Loan.
Here is the intro song:
Persona -Trinity Soul- Intro
....and here is the Zombie loan Intro for those who haven't heard it:
