In/Spectre's first season has landed on Crunchyroll, offering its full 12-episode run with both English dub and subtitle options. The supernatural mystery series, adapted from Kyo Shirodaira's manga, centers on Kotoko Iwanaga, who acts as a mediator between humans and youkai, solving supernatural crimes.

Brain's Base produced the series, which dives into urban fantasy tropes with a focus on detective work and mythological creatures. Kotoko, who lost a leg and an eye to youkai in her youth, becomes their 'God of Wisdom' and tackles bizarre cases. She soon takes an interest in Kurou Sakuragawa, a university student with a unique connection to the supernatural.

The series excels at building atmosphere and presenting intriguing, often meta, mysteries. Kotoko's sharp intellect and Kurou's stoic demeanor create a compelling dynamic as they navigate the hidden world of spirits. Its strength lies in its dialogue-heavy approach, dissecting folklore and the nature of belief.

With a MyAnimeList score of 7.46 and over 100,000 voters, In/Spectre garnered a solid following. The series concluded its initial run in Winter 2020, and a second season, In/Spectre 2, premiered in Winter 2023, making this a perfect time for fans to get acquainted with the foundational mysteries.
