Rebirth in Highschool dxd

My name is ryuji kazuma, or at least that the name I have this time around. this is actually my second chance at life, my choices were to either live a lazy normal life or take advantage of my knowledge to rise as a genius, all the while my only real preoccupation would be the weird sensation I feel inside my body. that lasted until I was in the park and I met a certain kid who resembled way too much to a certain echi protagonist. that moment I knew that I either became strong or I live a life that could end at any moment, maybe a little paranoid but I'm not risking it. —————————————————————————— warning: english is not my first language.
