rename hiyo_&_vivid -> hiyo_&_vivid!
rename hiyo_(hiyo_&_vivid) -> kurumiya_hiyo
rename vivid_(hiyo_&_vivid) -> kotomori_aya
create alias hiyo_(hiyo_&_vivid!) -> kurumiya_hiyo
create alias ayamorin_(hiyo_&_vivid!) -> kotomori_aya
Both characters are mostly referred to by nicknames, so create aliases to their full names.
