Manga Like Assa Jjintta Necromancer

On the planet Thebe, she was hailed as the “Lord of Death” and the “Living Dead”, the most powerful necromancer of all. With Serezia’s help, she managed to return on her own, but as a side effect, she lost all her power and took on the form of a frail young girl, even developing a fear of people. While in this state, she watches a live stream by a novice necromancer named Song Ha-Yeon and, in exchange for giving her advice, receives a magic stone imbued with fraud. She discovers that if she obtains fraud from other sources, she can use necromancy. Before long, she becomes entangled with Helena, an S-rank hunter and necromancer, and learns that her power hasn’t disappeared but is sealed by some unknown force, and upon seeing a status window appear, she realizes that if he levels up as a hunter, she can regain his power, so she resolves to become a hunter. “The ruler of the Underworld, who overcame even death, has finally returned to Earth. Though, due to the side effects of dimensional travel, he’s now a total loser.” (Source: KakaoPage, translated)
