'FLOW', the equation to create miracles.

I really love how Isagi, the main character keeps getting stronger in every volume. Peer pressure is so hard, and he always feel like he is not good enough (because the top 6's are so skilled). But, he didn't back down, his mind working faster, and he's improving his physical ability to be stronger than the top players. His adaptability is great. I love how the author also explain the 'formula' that he uses to adapt with the players and step up his game.

according to my calculations

∆ = b² - 4 a c
x1,2 = -b± √∆ / 2a
= i love shidou ryusei
