(Content from the Otherworld) ...Wait a minute. I need to clarify a few things first. First of all...I am the Sensei here, and you...are my 'students'? "Yes." Then what are you doing? What do you mean by "developing a special relationship with Sensei, and there's no turning back"? What do you mean by "spending long matches with Sensei..."? What do you mean by "your heart being stolen by the Phantom Thief of Hearts"? "Isn't this what you've been doing all along, Sensei?

Hello everyone, I'm Surtur, a professional toolman for five years... or even many. My contracting services include, but are not limited to, spreading the flames, destroying worlds, rescuing damsels in distress, playing cards with Slaanesh, slacking off, shipbuilding, driving, card-drawing, human-reason repairs, and so on. If needed, please post a notice in any tavern in Terra (the more shabby Terra) frequented by bounty hunters. Of course, I personally recommend contacting them through dreams.
