The only 'disappointing' part of Deathdrives are Ira and Vita IMO.
Unlike others, it painfully obvious Ira is for Episode 12 (marking timeline change), Vita is for Episode 13 (one episode King of Braves Isami).
Others died fitting their 'deadly sins' name with enough VA references for some; that reminds me, last memorial videos will be Ira and Vita.
