A Japanese dub of the series aired on television under the title Enmusubi no Youko-chan starting on July 1, 2017. Each TV episode was comprised of two ONA episodes with minor aesthetic touch-ups, formally concluding this season in its episode 6.
The Japanese and international versions of To Be Heroine (2018) feature a reduced runtime compared to its Chinese version, To Be Hero LEAF. Haoliners confirmed with ANN that, as was the case for Fox Spirit Matchmaker and Hitori No Shita - The Outcast (2015) , the changes were made so the show will fit into the Japanese television timeslot.
