So you're saying these things will happen in a single season:
 * Issei achieves Balance Breaker
 * Gremory-Sitri match
 * Juggernaut Drive
 * Loki and Fenrir vs Gremory team+Vali Team+Baraqiel+Tannin+Rose+Saji
 * Appearance of Chichigami's seirei
 * Leaders of the Hero Faction
 * Illegal Move Triaina
 * Gremory-Bael match
 * Crimson Cardinal Promotion
 * Issei's death
 * Issei's revival with a new body

Yeah. That's certainly possible.

~Inb4 those things can be skipped. NO. All those things has something to do with Issei's status when he fought Grendel.
