I like where you're going with this... This should be continued if at all possible. In some respects, this is similar to the story on Ao3 called "thunder of Zero". I would recommend reading if you havent seen it already. Trouble is, that one gets a bit too muddled and I think it would've been better to simply focus on the main characters...

Anyway, I quite like this and Hope you can continue at some point.

This was good. Should be continued

Gracias, excelente trabajo.

Zeruel is a naive KOS-MOS. In terms of badassery and emotionless expressions.

Hoh boy. Look out for poperty damage! These two make a TERRIBLE combination xD

This is such a cool premise, and you write it really well!

I can't believe you didn't pick the best girl, Ramiel

I love this story so much. The exploration of a character who has a completely alien mindset and giving Louise differing lessons via an absolutely obedient familiar is an amazing concept. Looking forward to see where this story will go as the it continues into other events from the plot.

This is pretty amusing, to see the character interaction my only problem is grammatically it's kind of painful to read in some places, but an interesting story so far nonetheless. I hope to see more eventually. Just find yourself a good and reliable beta and you can go pretty darn far.

While Directly it may mean Arm of God, the meaning is the Might/Strength of God.

Interesting concept though. I hope you continue this!

With the runes on Zeruel's hand being similar, yet different, to the known runes, I'm surprised that nobody has drawn the possible conclusion that Zeruel is a previously unknown FIFTH familiar...
