All my Seraphs are millionaires:

In Heaven Burns Red, the score challenge gives your characters a chance to defeat powerful bosses for various rewards, with a 'black trophy' being the ultimate award at 1 million points.  In addition, title badges track your highest score challenge score, and if it reaches 1 million you get the maximum amount of title badge experience possible from that field.  Title badge experience is necessary for the improved stats and eventual new skill slot (if you can reach the max title badge experience level of 10, which none of my seraphs have done.)  It's also necessary for master skills.  A common prerequisite for master skill unlocks is that your seraph at least be title badge level 5.  In other words, I had a strong incentive to get all of my characters, even my weakest ones, to a score challenge score of 1 million.

Originally I just wanted to get squad 31-E, the sextuplets, to 1 million, because they had scored 941k and were so close to succeeding.  I tried switching out Minori, the weakest link in the squad, for admiral Aoi to see if that could propel me to 1 million.  The answer was nope.  So next I tried using diva Ruka and yep, I got to 1 million.  Then I switched in Minori, taking out Yotsuha, so that Minori could also reach 1 million.  It still worked.  Diva Ruka was so powerful she could escort anyone to 1 million.  So I thought to myself, why not actually escort everyone to 1 million?

To do this I took my strongest squad, the plot squad, the fire squad, the 31-A squad, and took out Tama to make room for apprentices.  Then I had the 5 other squad members beat the score challenge boss on their own, including the all important diva Ruka who acted as healer, buffer, attacker and Sp point accelerator.  Ruka's ability is so powerful and all-inclusive that it turned out Tama wasn't even necessary.  The one seraph from the weak squads that was there just to get 1 million points on the score challenge never deployed to the front line so was never at risk.  Sometimes the 'apprentice' seraph did have a useful ability, though, like one that lowered the opponent's defense or fire resistance, in which case I did use them, resulting in ridiculous high scores like 1.5 million and once 1.75 million.  Almost twice the max score!  At that moment Yuki actually did over 100 million damage in a single attack.  She made even samurai Inori look weak.

This gets me one step closer to truly beating the game.  Now that I've beaten the score challenge section all that's left is the anachrony section.  Well, that and getting everyone's master skills, skill evolutions, levels and max skill levels. . .

Meanwhile, I finished my rewatch of Boku no Hero Academia Final and Kimi to Idol Precure.  Two more long great franchises I can say I've fully conquered, proving they're deserving to be in my rankings.  Now there are only 4 great anime series that aren't currently airing that I haven't rewatched in full.  I'm within striking distance of fulfilling my oath on this front as well.
