Ch. 321Holding the Line
Zenitsu tried to protect Aoi Kanzaki from Tengen Uzui, while Teiichi and Kanon returned to the Butterfly Mansion. Tengen asked Teiichi to support his investigation into the disappearance of his wives in the Entertainment District, and Teiichi questioned why he was needed.
- Zenitsu stepped in front of Aoi Kanzaki and challenged Tengen Uzui, but Tanjiro told him that Tengen was a Hashira.
- Tengen struck Inosuke for disrespecting him, questioned his training, and asked where Kato was; Tanjiro said Teiichi was still training.
- On their way back, Kanon asked Teiichi about becoming a Hashira, and he told her the title mattered less than using one's abilities well.
- At the Butterfly Mansion, Tengen explained that Hinatsuru and the others had disappeared while investigating the Entertainment District, suggesting an Upper Rank was involved.
- Tengen asked Teiichi to hold the line while he continued the investigation, and Teiichi asked why Tengen wanted him there.
