What if the goddess is also a reincarnator who knows that the hero party will become her enemy in the future and that's why she fought the demon god so early and by herself. To ensure the heroes never grow strong enough to defeat her.
Also look up the recent chapter where they tried communicating with her at church, think she's sacrificing herself to keep the demon lord busy all night 🥰
For a series based entirely on Competitive Sex™ of Occasionally Questionable Consent®, this series surprisingly has very clear boundaries. I'm enjoying this way more than I thought with each new volume. 😭
