For those who think that killing Sonneilon and Gressil by Tobio and Cao Cao is lame I have to put some things on mind

-Tobio Ikuse is veteran fighter with high technique of his Longinus, Canis Lykaon in Scythe form is able to even cut Gods so devil above maou class is still in reach

-Cao Cao is not as qualified fighter as Tobio but he has Strongest Longunus who is Holy Relic- a real deathly poison for even strongest of Devils

-Sonneillon and Gressil are newborn devils so they potential still has to grown but they dont simply has time to get experience in fights like Cao or Tobio
