In the era of samurai, a boy reincarnated from an Aikido master that died from age.  In the era where many villages were visited by the adventures. Born in the mountainside of the village, Mosho growing in the forest trains through the harsh conditions of a forest boy trains himself like the past life as an Aikido Master. From Rabbits to huge snakes that crushes stones like nothing, living without emotions. Know before Mosho went to the lands of the village, he made sure not to stand out wearing a fur jacket bigger than him. Walking through the village he found a really old man holding a katana being mobed. Just as calm as Mosho was, he decided to show his skills wouldn't be able to get the old man to teach him some swordsmen ship. As at the age of 15, he acted like a normal teen fighting off the three kids as an idiot would. And like that, he bowed down to the old man for knowledge. Just like that the two became buddies as if Moshofrom his past life used to talk to his only trust worthy friend.
