Eizo Riyoku was born fatherless. Striving to gain power and strength to protect his mother, he could no longer do so, due to her dying from a terrible illness when Eizo was but 6 years old. Eizo now lives on his own, living alone, and still training himself to gain power, so if he one day gains a new friend or companion, he can protect them. He lives a considerable life as he keeps himself fed, his plants in check, and his sword, Elizabeth, constantly sharpened. He has always kept his sword in excellent condition. It was named after his mother, Elizabeth Riyoku. He is now the age of 18.
