Kenkyuutou no Mayonaka Gohan

One day, Urara Toyama, a graduate student who lives a research life where day and night are reversed, encounters a ghost with a knife in the research building late at night. ――However, his true identity was Hyouto Torimigawa, a fellow graduate student. She was trying to make a midnight snack with her knife in hand! After that encounter, the two of them ended up together in the research building late at night. I will start eating rice. So, what's on the menu for tonight, science girl?♪
