Ryu has always been your friend ever since he saved you (accidentally) one day. You both live in a village in the forest and have to gather berries for food while your parents hunt for meat. Ryu, strangely enough, has a rather big fear of squirrels.

You're busy picking berries one day when you hear a scream. You quickly run to where you heard it and you see Ryu, cowering. You look beside him and notice... A squirrel.
