Not having access to the 'Tane and the Stars' story means we can only hypothesize. Tane might be a central figure, perhaps a creator or a protector figure in the story. Maybe he has some unique abilities or characteristics that are related to the stars. For instance, he could be able to communicate with the stars, or the stars could be a part of his origin story. But all of this is pure speculation in the absence of the actual story.
Since I don't know the exact 'Tane and the Stars' story, it might be about a character named Tane who has some kind of relationship with the stars. Maybe Tane is a mythical being who can interact with the stars, like using them for guidance or having adventures among the stars. But this is just speculation without more information.
May Tane Miyako and Hijishima Akuno were not the same voice actors. Mikoto Misaka was one of the main voice actors in the Japanese animation " Light Voice Girl " and Kikoto Ishida was one of the main voice actors in " Gate of the Stone of Destiny." Although their voices were similar, there was a big difference in character setting and dubbing style.

The nature of bat girl hentai comics is often considered inappropriate and violates the original image of the character. They usually focus on creating sexual scenarios and imagery that go beyond the normal boundaries of comic storytelling.
