Ok while the discussion has suggested Rin as the protagonist as this is the first time that the quest has been posted here something simpler and more general would be better to get people used to the format.
the story is told in short bursts in second person, the story will not move ahead without the readers suggesting action for the protagonist to take. The character of course has their own ideas but unless the readers prompt the protagonist to speak his mind about a situation he/she will remain quiet and directed by the readers unless they do something out of character. Only the basic description of areas or items will be made without prompting by a reader
