If you've got no better daemons, put all 3 of them on your def team... not worth leveling them up just to get the extra 1% divina atk reduction when fused... (if you don't max them out, they don't guarantee skill level up)

Maybe just use them until you have better daemons, THEN only you fuse them together. ;)
