I was reading a manga but I forgot the name of it so can someone identify it for me off what I can remember?

This is from the first couple of chapters....

Main character is a guy and he and some other people venture off into the forest to retrieve something or find out about something regarding the moon. They go into the forest and encounter the tribe that lives there which is all girls I believe. The queen puts them through trials to prove if they are worthy. One of the trials, one character has to find out the poisonous fruit from all the fruits and nuts in front of him, he puts it all in his mouth and spits out the one that is poisonous. The main character had to stick his hand into a jar and retrieve the white stone out of a jar full of black stones to test his luck. We find out the queen's sister is secretly plotting to take over the tribe.

If someone can give me the name of the manga that'll be great.

Thanks.
