Unfortunately Ninja
It is late in the evening in Hikari, Japan. Year 1992. The silence of a full moon night is interrupted by a sequence of heavy footsteps, then the noise of a broken door. This is all Akio was able to hear while in his room. But then he realized the noises were coming from inside his own house! He ran downstairs just in time to see three men disappear in a cloud of smoke, holding his unconscious mother. They were clearly Ninjas! Looking at an old photo gives him the idea that to ask his grandfather for help, he is definitely the right person for the job since he is the master of a ninja academy in a nearby town, and also, surely he would want to save his kidnapped daughter. So Akio jumps on the bus on a quest to find his grandfather and fix this mess… but it will certainly not be easy…
