Love it

For manga, with added fantasy in it:

-the villainess will crush her destruction end through modern firepower
-the savior's book café in another world
-the old man reincarnated as the villainess
-seijo no maryoku wa bannou desu
-in another world, I'm called the black healer
-higeki no genkyou tonaru saikyou gedou rasubosu joou wa tami no tame ni tsukushimasu

The last one is definitely my favourite, because it has more depth than the other isekai'd manga. The second one is my second favourite. The atmosphere of the manga is really relaxing, since the MC is like 30++ years old, so no unnecessary drama like little teenagers brings. Out of all the lists, I think the black healer is one I feel meh about. But some people liked it so.

Thank you so much! I'll definitely remember to read them all

- I shall survive using potions!
- Saving 80,000 gold for my old age

you won't regret it! (and yes the modern firepower manga is great i've read it too)

Thanks I'll check those out too
