since Jeremiah will likely swap the sword to a fake and deliver it to an S rank without knowledge of the author existing in the novel[ MC will likely run with Kevin toward the thief who already rip his mask and Monica will realize who has the real sword]. I'm assuming Ren is will use Monica to deal with Jeremiah while bringing along Kevin to pursue the path the thief went and Kevin is in for a big trouble..so much for a friend but I'm sure Ren will compromise with him with a creatable sword
