This is it, after all the trainings I have done for the past 12 episodes, my moment to shine has come. I will overcome my mental barrier and do my very best to beat my 12-episode-long green-haired rival and finally win this. Okaasan will be watching, and I will do her proud. My teammates are rooting for me, I can hear them, I could feel their support! I will...I will win this and end the series with another cliche ending and of course defy all possible laws of physics.
And all long animes because I lose interest quickly.
