So I've recently adopted a Johanna and was really excited to bond with my first servant, but it hasn't gone at all how I expected. She's been very distant and hasn't wanted to do anything that hasn't been popely or proper. I've been trying to encourage her to come out of her shell but I haven't been able to make it past that holy barrier.
I've heard that it's better to acquire servants in pairs and worry I made a mistake only adopting one for my first time. Do you have any suggestions of another servant I can adopt to help her feel more comfortable?
Servants are very social creatures, generally speaking. There's some Servants who do better alone -- perhaps even thrive -- but most of the time, unless you can dedicate huge number of resources to securing them the 100% perfect environment, they're at bare-minimum going to need play-dates with other Servants to fill their social needs.
So, to suggest another Servant to look at for a Johanna...
What about Mephistopheles?
If you need someone to help you loosen up, Mephistopheles is your guy. He's playful and fun-loving, and is great at drawing other's out of their shell with his tricks, jokes, and japes. I know, I know, you might be worried about how a self-proclaimed demon and a Popess can co-exist, but despite what he says, Mephistopheles Servants don't come from hell; they were produced by Faust, and would properly be classed as homunculi.
Really, the whole 'demon' thing is identity-seeking behavior, born from their creator not being happy with the batch and calling them failures at being homunculi. Legend has it that Faust was tricked by the demon Mephistopheles, but the truth is that Mephistopheles Servants tread the line between labels, and the story is just that -- a fantastical tale. Too much like homunculi to be human, made by mortal man so not demon, but unable to be a part of society just like demons because they can't be human. A Johanna, with her gentle demeanor and loving acceptance of others, may be just what a Mephistopheles needs to be comfortable.
A Mephistopheles may understand Johanna too, since she herself is more of a legend than a real person, defined by her saintliness and holiness rather than her own physical qualities. It's debatable if a real 'Johanna' ever existed at all! So much like Mephistopheles, she exists in a space between fiction and reality, struggling with her identity. This is probably the source of her aloof behavior; it's likely she herself doesn't even know who she is or wants to be.
Therefore, try a Mephistopheles today! Who better to assist your Johanna than a Servant who has forced the world to accept him as a demon-clown, because he wants to be more than he was created to be? And who better to pair with Mephistopheles than a Servant who does, deep down, actually like a few... explosions...
...did I accidentally just give helpful advice???
