Announced on the MASTERCUP Tekken Fight club nico stream were relatively minor stuff. The pre-order DLC character Eliza is being made available for separate purchase for people who didn't pre-order Tekken 7 for 500 yen which is roughly around $5 USD. She'll be available for purchase on the PlayStation store, Xbox Marketplace and Steam store on July 28th. Next up are free DLC customization items from the previous Taiko no Tatsujin collaboration with 10 pieces of customization to download. They're all old stuff from the arcade version of Tekken 7 but it features Taiko characters with hit & sound effects to equip on your characters. You'll be able to download the free DLC items also on July 28th alongside the public release of Eliza. If you happen to have a niconico premium (lol), you can re-watch the niconico stream over here:
