Hey srn its been a while since  i posted. So im going to tell you about my new manga , Hukaro padashi!! Hukaro padashi is a shonen bssed on the adventures of Rinkaku matabashi rinkaku is a holder of the element of lightning, he uses a fighting style called mikaku, in order for me to explain what a mikaku is i have to tell more about the attacks
You see the source of energy that fuels attacks in hukaro padashi  is called kubatshi, attacks in this universe are called arcenos, there are also 4 fighting styles  in this universe,  kotiki, a fighting style  based on physical  attack, mikaku:a fighting style  based on kubatshi  arcenos, kakuro: a fighting style based on defense, makuro: a balance of physical attack,  defense and  kubatshi  attacks
