http://www.mediafire.com/?jvzxlkp8vnsdh3xI highly recommend doujinshi by this circle. The stories are great and her characterization of Yamato is spot on and uninfluenced by the shitty anime. She's been around since the game originally came out in 2011. Her anthology (Meteora Stella) compiling 7 of her old work is still up for mail order on her website's order page (just use a service like goodyjapan, treasurejapan, or fromjapan to order since it doesn't accept overseas orders) It's really worth it to buy doujinshi when you're invested in a series.
