Kagerou Nostalgia 01
Synopsis: A group of warriors are reincarnated to once again fight their enemy. Think Gundam Wing, Fushigi Yuugi-style. (Hey, I can't think of a better comparison.)
Pro: ADV's production is top-notch. I forgot to mention this about Chrono Crusade and Aria, but I love how all of their manga come with colored pages. Their presentation is very similar to Del Rey with regards to SFX (translated on the side of the original kana) and with cultural notes at the end of the volume.
Con: I've already bitched about this before... I'm hoping somebody could elucidate me about the backstory of this particular series because I am totally lost. There's too much going on and there are characters who I think I should know, but don't. It's like walking in during the middle of a movie: I sorta know what's going on, but I'm still confused.
