I'm Standing on a Million Lives Vol. 6 (Kodansha, 2020)

The sixth Hero is Glenda, a fetching American who isn't shy about broadcasting her lack of interest in men. Through her, Yotsuya learns of other Hero groups dotted around the ""real"" world. There's a clear need to make contact with them--and so Yotsuya decides to...make a movie?! But in the ensuing sixth quest, the nastiness of the unseen enemy facing Yotsuya and Torii drive them to the brink! Volume 6 kicks off the Ihar-Nemore Drug War, a mission more difficult than anything that came before it!
