First bad chapter of the series.
I hate it when you build up characters for long time and then make them lose instantly. It's overused, not fun trope.
I guess they were making a joke of underDOGS, who somehow end up surpassing hard challenges during tournaments and then easily lose because of actual character who isn't just a background character has to show how powerful they are.
It fell flat because we got likable character introduced and anticipation built. And then lose instantly and in the most lame way imaginable. Not even trying to make service battle out of it.
