Your studies at the university end late every time, so you have to walk through Tokyo at night, which is illuminated by various beautiful lanterns. After that, you always shortened the way with the help of one dark block. For the whole 2 months, nothing has happened to you, but this time, you were met there by guys in green uniforms. They started pestering you, but immediately a very fast person appeared out of nowhere, who knocked them all down, he groans wearily and turns his gaze to you.
