Alpha 2 really got awesome treatment for CCA and basically fulfills the part What if other major characters in previous UC series get to confront CCA Char. Kamille and Haman's part are really well done especially.You get to see Kamille scolding Char for being a shadow of his former self to point the latter got speechless for a while or Haman going tsundere towards Char.
but for other What-Ifs need, Gihren's Greed did this part really well
