now that Kaguya has seen selner, she must have tracked her now. the otsutsuki are parasitic being that hunt for planets in lots of dimensions for powers. wouldn't it be interesting to see an invasion 🥰🤩😍
If you are planning to add kaguya in the novel then make MC his son or something or make her his big sister as kaguya being in a harem is just way too common and mc is just 20-30 year old while kaguya is 1000+old he is like a baby to her
