麻雀牌キーホルダー

I present my evidence, a mahjong tile pendant!
[Ransei]A mahjong tile pendant. What does it prove? Please guide me, Master.
[player]N-No, it doesn't prove anything. Sorry, I took out the wrong thing.
At most, this only proves that I'm a Jyanshi who likes to play mahjong. It can't be used as evidence. The key evidence is still in my pocket. I'll keep rummaging through it...
