There is a light novel that received an anime adaptation and is currently broadcast and has 24 episodes or 2 cours in its broadcast, entitled A-Rank Party wo Ridatsu shita Ore wa Moto Oshiego-tachi to Meikyuu Shinbu wo Mezasu or I Left my A-Rank Party to Help My Former Students Reach the Dungeon Depths! At the moment it has been broadcast, what’s more, the story plot in the anime is said to be too fast and difficult for ordinary viewers who are not used to this kind of story to understand.
Which will tell you about a character named Feldio Yuke, who is an Alchemist and also someone who gives debuffs to opponents and buffs to his party mates, until he left the strongest party and has now created a new party with 3 other adventure students.
Likewise for the 2 cours in the anime entitled A-Rank Party wo Ridatsu shita Ore wa Moto Oshiego-tachi to Meikyuu Shinbu wo Mezasu or I Left my A-Rank Party to Help My Former Students Reach the Dungeon Depths! This will later focus on fighting a Demon Queen named Lady Persephone.
However, there are also several other interesting things, because Lady Persephone is attracted to the character named Feldio Yuke, she can control the Dark Magic elements without any help in a very short time compared to several other characters.
