Kai is living a perfect life: getting a hundred percent on every test, mastering kendo, and never losing a game of Shadowverse. But what good is a world with no challenge for a genius among geniuses?
I won some and lost some. 
I'm not as good as you.
فزت وخسرت عدّة مرات، فلستُ قويّاً مثلك
Ich habe mal gewonnen, mal verloren.
Qualcuna l'ho vinta e qualcuna l'ho persa.
Non sono mica bravo come te, io!
Eu venci e perdi. 
Não sou tão bom quanto você.
