What would be the best isekai Harem? I thought... and this is what I cooked up. I hope its good.

Its Holo from Spice and Wolf, Emilia from Re:Zero, Lilia from Mushoku Tensei and Megumin from Konosuba.

They are all aged up to over 18.

Megumin has explosion magic as its part of her personality, but Emilia can't use magic and Holo can't transform, as it would take a lot more tokens to explain.

Try keep all the characters speaking at once, if one is forgotten you will have to remind the bot to bring them back. I can't really do anything about this.
