YunaGreyworth's manga / #receptionist(2)

Male mc died to early and was reincarnated with cheat skills as a compensation. Here is the story of the mysterious Receptionist elf girl. The fact that she used to be a guy is irrelevant. No fan service or gag about it. Surprisingly quite the serious story. She is OP but never participate in combat, only give super useful advice. I like that It's not cliché but at the same time the plot is very light with heavy discution... not sure where to categorize this...
