https://www.youtube.com/watch?v=euzRjM4bfcQhis theme is playing during our battle. It's actually pretty saddening. He's desperate, under pressure to succeed. Hes not a bland nice guy, hes a hard worker and is serious.
He works as hard as us, and has character motivation to beat his older brother. This is his self worth on the line.
Meanwhile, we have no character motivation. and we beat the crap out of him lol.
No other rival has had this development, so its natural we felt sad this time.
