Monacrow

Monacrow is the ship between Reaper Crow and Monarch.

Aaaaand I'll probably need to ask Cleaver about this ship because I know nothing about it XD

It's one of the very first ML ships, as there were even shipping moments in the very first ML RP thread.

It became canon when Reaper and Monarch revealed their identities to each other and Reaper finally got up the courage to ask her out on a date. He fainted when she said yes, and they've been dating ever since.
