first : he is supposed to be a loner because he is send to different worlds and doesn't want to miss his friends, a self called loner BUT his kouhais, that never before visited another world and that in real life have know him for a relative short time, are desperately in love with him?? He saved them once in the past but most of the time he ignores them but he is still their god? Is this the senpai power?
Two: The knowledge of the protagonist is supposed to be boundless and his spells of a completely different scale, he even creates a spell that AUTOMATICALLY searches and saves the true history of the world for his personal use only, but with just a glimpse the queen sees through his camouflage, what the heck queen were you actually more powerful than our one-man-army of gods protagonist? But then why not use your seer talents to save your country instead of beg the help of a random otherworlder?
