A Wild Last Boss Appeared! Vol. 3
野生のラスボスが現れた！Yasei no Last Boss ga Arawareta!
this series is the equivalent of boiled, unpeeled, unflavored potato. if that sounds thrilling to you then go ahead and dig in. if you really are just starving for litRPG isekai and have absolutely nothing else then you might get some satisfaction from this.
thank you so much for the upload!
