The S-Classes That I Raised: An F-Class Hunter. And on top of that, a F-class older brother who can’t even begin to catch up to the heels of his amazing S-class little brother. After living a life that fell to pieces and even destroying my little brother’s life, I picked up the following resolution: “Perfect Caregiver”. That’s right, this time, instead of becoming mean, I will quietly support those who are more capable. Is what I thought… but the S-classes are kind of… weird.
