Riku

Riku is a white Samoyed dog gifted with the rare ability to speak, who willingly accompanies the swordswoman Shizu across countless lands under the title of loyal servant. Despite his naturally smiling face giving off a cheerful impression, Riku is in fact deeply composed and analytical, often offering Shizu candid and insightful guidance throughout their travels. As the primary narrator of Shizu's story arc, he engages in witty exchanges with the motorcycle Hermes, and later becomes the most trusted guardian and companion to a young girl named Ti.
