 * # suddendeath
 *
 * Generate an ascii art of sudden death (突然の死)
 * from specified `text`.
 *
 * ## arguments
 *
 * - `text` is the text to die suddenly.
 *   its default is `'突然の死'`.
 * - If `proportional` is `true`, it returns
 *   the text for proportional font.
 *
 * ## results
 *
 * A text of ascii art of sudden death.
 *
 * ## examples
 *
 * ```
 * var
