Interesting concept, I rate this manga as an 8/10, it's just a shame that it hasn't been updated in 4 years.
Having a whole family reincarnate into a fantasy world family is pretty novel.
The plot is a bit silly at times ("Put this spider on your head to get stronger!"), but the author is having fun with the possibilities, and it is pretty novel, so it feels endearing.
The translation is slightly lacking at times - it feels like the lore was probably better explained in Japanese - but it's still way better than current AI.
