Ch. 321DanMachi: My Familia Is Full of Heroines from the Ten Thousand Worlds!
Seitenshi worried that she was unnecessary on the Dungeon expedition, but the others reassured her and explained that their weapons had been chosen with Lord God's help. Meanwhile, Haimo and Hephaestus worked together to forge deep-floor ore while Loki struggled to keep the furnace hot.
- Seitenshi said she felt helpless on the tenth floor, and Onigawara Rin, Kikakujō Mary, Hanabishi Warabi, and the others encouraged her and called her an indispensable member of the Familia.
- Hanabishi Warabi worried that Enju Aihara's boots would wear out, but Onigawara Rin said Lord God would provide suitable equipment and showed off her Famous Sword: Black Crow.
- Kisara Tendo asked about the swords, and Hanabishi Warabi explained that Lord God had asked the captain of the Hephaestus Familia to help select them.
- Haimo hammered heated deep-floor ore in Hephaestus's Workshop while Hephaestus turned it with tongs and Loki pumped the bellows.
- Loki complained that the work was exhausting, but Hephaestus warned her not to let the furnace temperature drop or the ore would be ruined.
