18 for the 'waifu' and no harem please Too cliche and kinda takes the immersion out of the story

Well this is easily one of the besf fanfics available and even though there exists fan fantasy elements it's much more followable and readable compared to the masses (which is basically horsesh*t and that says a lot) if you have low to medium expectations it's good but don't expect too much. And teaching does play a role in mc's growth but the missions and rewards doesn't match or mc has the SS+ Rank passive *author's special plot armor* compared to the usual SSS+ Rank Original MC's plot armor Overall a nice read give it a shot If you don't like it after 20 chapters I guess this ain't for you mate.

Soldier can I have the report whether our comrades can pass or not

Food for thought
