Kagali/Chronology

The Octagram Soars Brightly Arc
After failing to infiltrate the Western Saints Church, Laplace returns to report about the encounter with Roy Valentin to a mysterious man and a female Elf, revealed to be the former Demon Lord Kazalim, having been successfully resurrected in the female Homunculus Elf body. After hearing Laplace's story, Kazalim, having now taken the identity of Kagali deduces that Laplace encountered Demon Lord Valentin and reveals of how he and the Bloody Lord often battled, during his prime, even stating she lived through three of the Great Tenma Wars that occured every five-hundred years while explaining that their battles were the reason why the custom of calling a Walpurgis Banquet began. After discussing with the mysterious man, Kagali theorizes that Demon Lord Valentin could be the Holy Emperor himself.

When Laplace asks the man and Kagali about Clayman's whereabouts, they reveal that their plans failed, in particular about Clayman's Awakening into a True Demon Lord using the Souls of the fallen soldiers. Kagali tells that apart from their strategy to use Farmus's soldiers, they had also planned to use Milim to kill the humans residing within Eurazania in order to allow herself and Clayman both to Awaken into a True Demon Lord, though the plan failed due to Milim declaring war on Carrion and granting him time to prepare. Kagali and the man tell Laplace about their plan to allow Farmus kingdom to invade Tempest and planning to negotiate with the victors. However, after recieving word from Clayman, they learn that there were no corpses left, with the Curse Lord believing the corpses to be used in summoning a powerful monster as well as how there were no Souls left to harvest. Laplace thought Rimuru used the Souls to Awaken as a True Demon Lord, though Kagali dismissed the claim, stating that it was not possible for him to be a Demon Lord Seed. The mysterious man tells that not everything was a failure as through the war they were successful in weakening Farmus kingdom.

Kagali, upon being asked by Laplace about Clayman's whereabouts tells that he was currently awaiting further orders and was told not to do anything till then, stating that the Eastern Empire was already preparing to invade the West, and all they had to do was to avoid conflict with the Monster Nation. The mysterious man believes that with Farmus Kingdom defeated, the Western Saints Church will take action against the Jura Tempest Federation, though he is confused as to how they could lure Demon Lord Valentin away from the Church to allow Laplace to infiltrate it easily. When Laplace suggests convening the Walpurgis Banquet through Clayman, supported by Milim and Frey, Kagali and the man are pleased to hear this and decide to try to lure out Hinata as well, while asking the Wonder Pierrot to infiltrate the Church once more.

Saint-Monster Confrontation Arc
When Laplace returned from his inflitration mission after killing Roy Valentin, he reveals to the mysterious man, Kagali and the others that Clayman was killed in the Walpurgis Banquet, with Footman accusing Laplace of lying. However, they knew the Wonder Pierrot was not joking and that their friend had indeed died, with Kagali stating that she lost her connection with him the previous night and that she does not want to accept his death. The mysterious man laments, stating that it was his fault and that he should have planned much more cautiously. When Laplace begins to insult Clayman, stating he was too stupid for his own good, Footman is enraged at this, but Kagali calms him down. After everyone regained their composure, they began discussing what to do next. Kagali reveals that Clayman's castle fell during a single evening at the hands of a small force sent by Rimuru. This was the final straw that made them realize that for now they couldn't do anything. When the man reveals that there is a way through which they can take revenge from Rimuru for Clayman's death, a confused Kagali asks about his plan. They all agree to stay low for a while.
