Trivia

 * Ryota is a Atheris hispida, also known as a Spiny Bush Viper.
 * Ryota is a variant of Ryouta. Meaning (涼, ryou) "cool, refreshing", (亮, ryou) "clear" or (良, ryou) "good" combined with (太, ta) "thick, big". This matches him as he is strong, thick, and big for a snake summon, but is also good in the inside.
