Do you really want to put our precious Yuu-chan through that? Actually, Yu is now a namanari (someone with two personalities in the process of becoming a demon) which started near the end of the Nagoya Arc. Basically, Yu chose to erase the rest of his humaity by becoming a seraph so he could be strong enough to protect his friends from Seraph!Mirai and the Demon Army. Then Asuramaru appears to remind Yu that he does not want to destroy humaity, hence he tells Yu that he can suppress the seraph's power by becoming a full demon. Yu would grab his cursed gear and would turn into a demon.

During the three month time jump between the end of chapter 41- the start chapter 43, Yu has been turning into a demon and would spend an additional two minutes each day. Thankfully Ferid gave Yu a medicine that will keep the demon at bay, but is most likely only a temporary fix.

Also according to the nanamari page, humans can also become demons by getting inflicted with a demon curse whether it be by touching unrestrained cursed gear or being born with one from a demon-possesed parent.

Sorry if this explaination was long.
