He made a costume for him, a normal shirt and pant. He always loved swordsmanship and got inspired from "Sword Art Online(SAO)". He got an old katana from his neighborhood but it was rusty and had blunt on the sharp edge. He managed to clean the rust off and sharpen the sword a little bit. He used that sword to master sword skills. Sword skills are complex combat moves which were very powerful but not everyome could use it. Because he had an old rusty sword, he could only master Storm technique but the sword is weak and it can break if he used it more than 5 times.

His neighbour namely Arthur, an old guy - Former Swordsman, taught him this technique

He wasnt able to use it and he thought he can't use sword skills.
