A mid-rank soldier who died during the Demon race invasion, woke up back in his past as a baby. To avoid the chain of tragedy of this war (lots of dead him included), he will prepare for it with maximum efficiency.
MC was OP in 1st chapters but went back to strong “only” later on. Other characters are interesting and unlike most Isekai, strength level is quite balanced. Like MC isn’t always the one shining or leading even if his here, in a good way.
Child Mc but not fluffy.
