Mipherius/Chronology

At some point, Mipherius came into conflict with Kazuma Satou and his party of adventurers in their world. Being envious of his perceived "harem", Mipherius flew into a rage and attempted to kill them all. However, when faced with the 'Explosion' of Megumin, he found its power a bit too much to handle and opened up an interdimensional portal to contain the blast, unintentionally sucking Kazuma and his friends into the Central World in the process.

He would attempt to provoke Gabiru into all out fight with Kazuma but Rimuru quickly broke up the fight. Later on he would summon in Cabbages to attack Rimuru and Kazuma's party which ended up in failure.

Later on he would reveal himself and attempted to destroy them personally, but Rimuru used a barrier to stop him from phasing through their attacks, Out of desperation he transforms into Charybdis Toad and attempted to attack Tempest. With the effort of Rimuru and Megumin's combined explosion spell, Mipherius was finally ended once and for all.
