YAIBA: Samurai Legend - S01

Deep in a tropical jungle, young Yaiba Kurogane diligently practices swordsmanship alongside his father, Kenjuurou, completely unaware of the modern world. But one day, the two end up in a container on its way to Japan. There, they meet Kenjuurou's old rival, Raizou Mine, and his daughter, Sayaka. With no other options, Yaiba agrees to a deal with the Mine household: if he beats the strongest student in their dojo, he can stay. Using his distinctive skills and extraordinary strength, Yaiba earns his place. Wanting to fight more powerful enemies, Yaiba follows Sayaka to school, where he quickly loses to Takeshi Onimaru and acknowledges him as his new rival. With Onimaru inheriting the sword of his bloodline and gaining demonic powers, Yaiba must train to become even stronger and beat him for good.
