I really miss this character, especially in Shadow Hearts II. There is no way that he will be back in any game, though.
I had tried translating the Japanese game for the Western gamers, and I learnt a lot on the work that I had done. Not just about Japanese, but about part of the European stuffs and words. It was indeed a great pleasure to learn so many things by drilling into one of my favourite games.
And yes, I still miss the Shadow Hearts series.
