Very odd crossover. Whenever I see something like this I can't help wondering if there is some connection I'm not catching, but it's probably just random.
Miracle Sanae and "Hax Sign Reimu" on the same team? /facepalm
In anycase, If this was a Ron on Marisa's 4-pin, this would be a minimum Haneman hand (12000pt Ittsu, Hon-ittsu, Yaku-Pai), not counting any other fan boosting conditions, doras Ippatsu etc
