Rika's job with J League takes her everywhere in Japan, and last May she went to visit Tottori Prefecture, which is the least populated
prefecture in Japan (only about 585,000 inhabitants), located on the Sea of Japan side of Honshu.
The team there is called ガイナーレ鳥取 / Gainare Tottori , and they are a J League Division 2 team.
The word Gainare is a mashup from the Japanese word 大きい, pronounced "Gaina" in Tottori dialect (instead of Ooki in standard dialect), which means 'great' and the Italian word 'sperare', which means hope. Put them together and you get 'Gainare' (great hope)
So everybody must have had Great Hope from Rika's visit, including costume dude, who is known as 'Gainaman'
