the 6th daemon is crew support :)  (you can do that by clicking 'Ask a Crewmate for Backup' button on battle page), you can use that once everyday

Crew support will give you additional damage to your attack, half of the total attack of the daemon your crew use as lead that you choose

btw don't forget to hide the username if you post a screenshot of other player's team ^^;;...
