Sakura and Shirou
Sakura gasped with worry as she opened the door to find the window open and Red gone. However, before she could do anything, she noticed the note on the bed and went to pick it up.
I'm gonna get some mushrooms. Don't look for me! it said, the silly drawings showing the girl's childish nature.
Sakura smiled softly before sighing with relief, glad that Red was OK and hadn't run away from them in anger or shame.
"Senpai, Red went out to get something", she said as she entered the room, handing him the note.
Shirou smiled as well, putting it down on the table.
"We'll need to get her a key so she can get in when we're not here", Shirou said.
"You wait for her", Sakura replied. "I'll go and get one cut."
With that, she headed out the door, going towards the locksmith's to get another copy of her house key cut.
Rider
After heading back home, Rider said goodnight to her master and then settled down to read one of her many books. The morning after, following breakfast, Rider decided she felt like going for a nice bike ride, so she headed out on her new bike at high speed, riding over rooftops, through woods and generally enjoying herself.
