Black Legion: Starting from the Eye of Understanding

Lin Xiao traveled through time and became a first-year student at Fudomine Middle School in the world of The Prince of Tennis. Good news: Once you awaken the [Pupilla of Understanding], you can learn whatever you see, and you can also teach it to others. So, he brought Ibu, Kamio, and Ishida, together with the newly transferred Tachibana Kippei, to overthrow the old tennis club. Ju Juping became the minister and he became the special adviser. Kamio learned "Sonic Sprint", Iwu awakened the "Eye of Insight", Ishida hit the "Ultimate Wave Ball"... What? Is the opponent Rikkai Dai? Qingxue? Ice Emperor? It doesn't matter, he has an entire anime universe in his arsenal of skills. "With the eye of understanding, all things can be taught."
