@SuperOniichan It's an ad to promote the release of vol 8 of JnM and vol 2 of uchuu toka
And Baka is the protagonist of JnM, or at least the icon of the manga. All promo centers around her or the trio as a whole
@Say I know that Baka is the most popular character and Japanese fans even joke that this is a manga about Baka's harem, but after watching the anime and past volumes, it seemed to me that Ota is a distinct protagonist and avatar of the author.
@SuperOniichan didn't get that feeling myself. I felt like baka always carried the manga and anime. The best thing about this manga is that you can argue that any of the cast is the protagonist, since they all get a decent spotlight.
@SuperOniichan Ota is definitely the author's self insert, that's confirmed. Pretty sure she even based Waseda on her husband and then had Ota fall in love with him.
@Say I dont know. Ota is the only character whose personal life we have seen in both senses and she is the only one of the main trio whose personality is not defined by her quirk as the main personality trait. However, we can argue about this forever.
@Darklight99 I know, in one omake, she even drew her trip with her husband, which out of context looked like Waseda's trip with an adult Ota.
