hi
iam trying to find a manga i was reading at one point but i can't remember its name

details i can remember about it:
there not many vol of the book i think 3
vol 2 some of it or all is set in a forest
in the second vol the main character + him comrades must do 1 test each
you find out that there is one character that can't eat poison that's how he passes his test


that's all i can remember

if anyone can help me i be thankful

this is a shot in the dark, but Takeru - Opera Susanoh Sword of the Devil

that the one thank you so much
