Not very interesting, the plotting is full of "Yes, but unbeknownst to you, I just..." which feels like a cheap cop-out. And the designs are positively outdated too. It also doesn't help that I don't have any sympathy for the main character.
Gunslinger Stratos: In the future, Japan has been broken up into several corporate states. Gym class trains the students for gun-and-sword urban warfare. Our main character tries not to stand out, but when he and his girlfriend are transported to 2015, they have to use their skills to stay alive against a mysterious gunman -- who turns out to be his doppleganger!
SciFi, mystery, time travel and running gun battles? Sure!
Plastic Memories: Tsukasa starts at SAI corporation, which sells 'Giftia': androids with a synthetic 'soul'. However, they only last nine years and four months: after that, their memories and personality start to degrade. Tsukasa is part of a team that has to recover the Giftia that are running out of time, but that's not always easy...
A really interesting premise (the Giftia know they will be decomissioned, and the team always pairs a human with a Giftia...), which turned out to be (surprisingly?) full of compassion and empathy. Recommended.
