In order to practice and test your rewinding ability, Moses will show you a photo from the anime No True Samurai and then ask you who killed Swordmaster Frostbite. Max will correctly guess that the answer is somewhere in the lab, but in order to find it, she must explore a bit.
First clue is not too far away. From where you're standing, turn around and go to the back of the lab. You'll find a poster for the anime on the wall, and on it, a suspicious looking schoolgirl. Unfortunately, there is no name visible yet - you'll need to keep searching in order to find it.
After that, find the stairs and make your way up to keep searching for more clues. Upstairs, Max will come across the figurine of the schoolgirl character. Pick it up and rotate it to examine all sides. On the bottom of the figurine, you'll find the name Mina Hiramatsu printed on the base.
Now that you know the name of the killer, go back down to Moses and use your rewind ability to return to the moment when he first asked the question, select Mina Hiramatsu as the answer and solve the puzzle successfully.
