after this baby issue, Chiho stepped aside or agreed on an already-lost race vs Emi for Maou?
Dunno
But the main problem of chiho that she is weak, she can not fight (except the moment she was lent the power by emi's mother) untill now (arcording to the light novel) she have not had any significantly special skill or power in fighting yet. Hope she can do something in the future, if not her deathflag 80% will be raised soon
