The Arcana is one of the themes of the series, hence why I'm mentioning it. It also revolves around forming bonds/friendships/relationships with other characters. A friend showed me them. There is one more thing, but its a spoiler to your VN, so I won't say.
Ah I see. I based the Arcana off of the Tarot Cards due to really enjoying the idea behind them. I will have to take a look at that game though cause it sounds interesting!
