In Homage to Tomorrow's KMS Conference..

By IAmFear's description, not only they work the same way as current familiars do, but they get stronger as they fight by your side and then they can defend your pride by kicking other people champion monsters so you can actually create a true bond with your familiars this time. Now let's hope the fighting system is something fun and deep.

Well, actually, I think I might have been mistaken.



This image led me to believe that you could summon your monster along side you, but that's probably a monster that you're attempting to capture with this skill:

Monster Trap
Description: [Max Level: 3]\nUse a Capture Seal on a monster and then attack it to try Capturing it.\nHunt monsters to increase your Capture level. Using the skill will reset your Capture level.
Info: pvp = 0, type = 2
Delays: capture - 990 ms
Animations: level.1.ball, level.1.hit.0, level.2.ball, level.2.hit.0, level.3.ball, level.3.hit.0

I believe the symbol above its head is actually the "Capture Seal", rather than an indicator of a captured monster.

Even if you could summon them, though, there's nothing to indicate that they would attack with you, they mostly just leech your EXP, and pretty much all the battling has the monster in Card form anyway.
