Dreamitchi/Dazzilitchi can be obtained by raising your Feature CD up to 4th Gold. Then, you must go to the Gotchi Records Shop, and click the Special section. Exchange your CD for a Boys Destiny Star (for Dreamitchi) or a Girls Destiny Star (Dazzilitchi). Then the item will be sent to your apartment, and you can send it to your Music Star. Only boy characters can use the Boys Destiny Star, and only girl characters can use the Girls Destiny Star.
