s05e13 — `Tis An Honor!

@shei350: I think if you skip the arches, then 60-70 percent of the series can be missed) but these arches are too "special" - a villain appears, kneads, someone gets a lot and he/she is dying, the main villain reaches its apogee, then memories, Sakato's speech, the villain is reeducated, everyone disperses after receiving a bunch life HP.

@TheHeretic: well, Gin just knocks down some villains, not everyone leaves, heh)
But in general, the Shoyo mega arch is my favorite of all the tons viewed, so I cannot adequately assess it 100%. Naturally, there are cliches, naturally the Gene prevails in the end, but all these little details, which then add up to one picture, are very good.
