Thanks to the game having kana translations above the kanji signs, I was able to clear that one! Man, I still have traumas from Nanashi no Game's similar kanji-based puzzle.. Ni no Kuni was a blast! Inazuma Eleven I never had the strength to actually play, didn't really like the first one..
Anyways, man it took me a long time to find the demo. Any of my regular sites didn't have it..
