She is probably just trying to mess with you BUT you should go get checked for STDs either way . If a partner is unfaithful , get checked . Better safe than sorry . Do not message this woman back , do not meet with your ex , do not pass go . If you somehow end up actually having an STD , maybe pass on that information , but I don ' t think that will happen . In summary , get checked , do not talk to ex or other woman . <| sep |> Several things wrong . First as uaztbeel points out servants require mana to stay in this world and attacking their materialized body attacks their mana pool . Secondly servants do not need conceptual weapons to be harmed in the physical world . While they have a spirit core that ' s outside space time , thats copied and what ' s summoned does require mana to stay alive . There ' s multiple instances of servants being harmed without NP . Moreover saitama believing he is human is pure unreliable narrator bs that every other character calls bs on . He ' s so completely beyond regular human it is a farce . There is no mystery black box to damaging servants . They take conventional damage that is repaired by healing magic and mana . They bloody have internal organs and bleed for crying out loud . You ' re writing 100 % bullshit .
