The official site of the anime adaptation of the manga, written and illustrated by Yukiwo, Jashin-chan Dropkick has shared a trailer for the 2nd episode of the project's 3rd season, which will air on July 12th in Japan. The trailer features a character that fans say reminds them too much of Kanojo Okarishimasu Mama Nanami.
The synopsis says: "Now haunted by the skies, Pino is increasingly afraid that he will soon be exterminated. Meanwhile, Pino goes to the park and hears Yurine's angry voice. When a surprised Pino looks away, he sees Yurine's fist, aimed at Jashin-chan, strike her. Yurine then turns to a small girl who keeps an unchanging expression on her face. This little girl is Lierre-sama, one of the heavenly butlers who came to earth...".
True, it's not that Mami-chan but the character of Lierre-samaa who already appears in a special (i.e. non-canon) episode titled "Chitose Chapter' and premiered in Japan on 30 April 2020. However, the coincidence is rather strange, especially since from the second season of Kanojo, Okarishimasu is on air at the moment.
