- "There is only one correct path to the ultimate Devil-Type evolution. Find 'Shyovasli' or the path will never open."
- —Excerpt from Sage Eneomaos
The Chauve-souris (ショヴスリ Shovusuri in the Japanese, French for "bat", meaning bald mouse) is the main weapon Isaac uses during his first battle with Hector and during the battle with Trevor. It is essential in getting the final evolution of the Devil-Type Innocent Devil, The End.
The deciphered message that only a Tiramisu Fairy-type ID can read is in the Infinite Corridor. The Chauve-souris is mistranslated as "Shyovasli" in the US version; it correctly says "Chauve-souris" in the European version.
