Jahil/Chronology

Ambitions End Arc
Jahil, dormant inside the body of Footman, is awakened by Feldway. He proceeds to pierce Yuuki Kagurazaka through the chest in the confusion and once more declares his existence to the world to the shock of Kagali and Sylvia. He briefly battles with Yuuki and turns Footman's power into his own. The Ultimate Skill 'Raguel' mixed with Jahil's pre-existing fire abilities to create the Ultimate Enchantment 'Agni, Lord of Blaze'. Jahil used his previous experience killing Gaia to counteract Yuuki's Anti-Skill by using an attack that combined skill and aura, creating a massive fireball that would annihilate everything it touched aimed right at Yuuki and the rest of the Clowns.

Royal Capital Disturbance Arc
Jahil's fireball is unleashed and nearly destroys Leon's castle. Rimuru Tempest arrives with reinforcements and 'eats' his fireball with the power of Azathoth, narrowly saving Kagali and Tear but just a moment too late to save Yuuki and Laplace. Jahil proceeds to engage in combat with Benimaru and maintains an advantage after summoning his 'Origin Blood' spear, a God-Grade weapon gifted to him by Twilight Valentine. Feldway fights Rimuru and eventually calls for a complete tactical retreat, resulting in Jahil and co being sent to the Heavenly Star Palace. At the Star Palace a meeting was held by Feldway to assign a proper structure and hierarchy to their forces and Jahil was selected to be one the Three Star Admirals of the army. Jahil is given a large army of angels and begins a campaign on the western front.
