Get pass the room where your lunch is:  Go to the changing screen and press X. You should get somebody to talk, but not Kagome.

Michiru watches Kagome take bath:  When you first arrive in Rindoh Village, you will get a day off. Pick Kagome. She then tells the main character (boy) not to peek, and then he gets stressed.

Sesshomaru ending:  When you get interval scenes, sometimes it will say, "Would you like to spend the night?". Respond "No" and you will not get an interval scene. If you say "No" to all of the optional interval scenes you should only spend one scene with each of the five main characters. When you switch places with Utsugi and you go to Naraku's castle, the game gives you the option to find the others or tell Sesshomaru about Rin. Choose "Tell Sesshomaru about Rin". Then, do all of the random events with Sesshomaru. Random events are when question marks appear on the map screen (instead of exclamation points). The first is in "The Field of Ignorance", the second time around go to "Road to Kasasagi", and the last time go to "Forest to Tsuzumi". In all of these places, if you wander around, you should find Sesshomaru and trigger an event scene. After you do all of this, Sesshomaru's picture should appear when you save your game. At the end of the game you will get the Sesshomaru ending. Note: You may have to do this twice. The first time to unlock or enable it and the second time to actually get it.

Mystery events:  To unlock mystery field events for your bonus, you must raise your seeds well. You can then harvest their fruit. When the time arrives, you will receive fruit items from the field guardian. By using the special fruits you can trigger secret events.
