Here's a challenge by Manda Jr (who can't post it himself so I do it for him). Rules and summary inside. Please leave a review if you take on this challenge.

A chance comment by Kiritsugu leads to Shiro trying his luck with the renowned psychic Genkai. Too bad no one told him that she was hosting a tournament the day he went to visit! Now he has to deal with having psychic ability on top of being a Magus, and the adventures that come with befriending known punk Urameshi! Can Shiro unlock the truth of his heritage before it's too late?
