Sandro needed to stick to the actual facts of the universe instead of constantly adding new bullshit and upping the stakes with worm drama.

Kengan is the top dog of underground fighting orgs because it's used to settle financial disputes between multibillion dollar companies and was anything goes, it needed new blood so it did the deal with Purgatory throwing a half-assed "elite" group (limited by faction politics) against their absolute best and winning. The arcs after this should've been about Kengan becoming partially public facing with some of the fighters doing Purgatory matches and some Purgatory fighters going underground and getting recruited by corporations to join the ranks of the corporate fights and Koga being one of the guys stuck in the middle needing to prove themselves because he wasn't a super elite like the Kengan Ashura cast.

Shit like the new generation should've mattered way more as a mix of Kengan fighters that got scouted by the secretary girls and are looking to get proper sponsorship instead of associating with Yamashita, Purgatory fighters that got to shoot up under the new rules, and new corporate fighters.
