I don't know about the rest of you, but the first thing that struck me about this as disturbing was how responsible that Marisa seems. I mean, feeding her kids? Wtf?
We have presents ready before they come back Mama will definitely be surprised(not sure) surprised(not sure) Work hard alices!
Everyone can really really take it easy here This is really the easy place Everyone, take it easy!
(not sure) Construction location Keep out
Today after returning from a stroll the nest was gone The inside of the nest was a really easy place. The huge amount of food stored, the loads of treasures The location of their nest.. the shape of yesterday's nest is gone Replaced by a huge fence with a unreadable sign
The chair and table created by mother and the life long stored food. The (semi?) shells collected by all the koyukkuris working together, and Mr. Flower to be given as present to mother. While hunting, the good/kind children left behind to watch the nest.
Easy stroll -> Enjoyable stroll easy! Take it easy -> Following easy!
(don't know) -> I'll (take care of)/(watch) the house easy!
Us reimu's precious stuff -> It's us reimu's treasure
Mama will definitely be surprised(not sure) -> mama will definitely be delighted surprised(not sure) -> delighted Work hard alices! -> We worked hard collecting!!
(semi?) shells -> Cicada Shells (Cicadas are just something 'notable' in Japananese culture, it's that little bug next to the reimus)
The sign is:
[Overbearing Devil House Construction Site Keep Out] or [Emperor Mister (Onii) Construction Site Keep Out]
Also, I changed the text at the bottom slightly for better coherency in English. I hope it isn't too off:
"Today, after returning from a stroll, the nest was gone. The inside of the nest was a really easy place. The mounds of food stored, the loads of treasures, The location... but now, only the shape of yesterday's nest remains. Replaced by a huge fence with an unreadable sign.
The chair and table created by mother... The life-long supply of stockpiled food... The cicada shells collected by all the koyukkuris working together... And the Mister Flower to be given as a present to mother.
The kind and obedient children were left behind to watch the nest while the rest went hunting.
