Thanks for the chapter!
Ookkaay. Message said spell about 70% complete, so does that mean they didn't murder MC but left him there so his negative emotions would rise making Yuno stronger until spell completed or MC died? In any case, hope those wolves are low leveled as 1 HP won't stop them from killing him unless are too shocked by the damage to finish him off.
@SpookyPants Probably picked him as nobody other than them would raise up a fuss over his disappearance, least likely to go with plan, and his teacher could cover his role in the party while the rest didn't have someone who could fill their position. Main reason was likely due to his shy and blunt honest personality he'd be easier to trick and fall harder as the more bitter the betrayal the more negative emotions he'd feel which the ritual would change to even more power for the hero. Also, he wasn't a weak member or wouldn't have been part of the hero's party in first place. Then there is as Up_to_no_good said about the storyline.
