Well... in the previous world I was in, it also brought people together like this. I made a contract with a Servant.

[ And it was... definitely something. Weiss wanted to be stronger, so the contract wasn't how other contracts would normally be! And she even fought her would-be Servant then prior to the whole agreement since that's how summoning works for Weiss— the creatures she's able to summon are ones whom she's defeated in the past. Of course, she was unable to defeat her Servant then, but it was a close fight! And a formality, at best. ]

After finding myself here, our contract's been severed.
