Sorry, I don't speak that language. I only speak English and Spanish, so I used Google Translator to understand your message, and it looks like this:"I have a mission to help the heroine. But after helping the heroine, the system still tells her to help the heroine."
If you're talking about saving Rin, this part of the game is still under construction, so you will need to wait a little more to be able to save her; right now, there is some advance for this rescue, but only around 50%.
