Recently went to Kura sushi for the Hololive promotion. I wasn't able to get one of the souvenir as they apparently sold out rather quickly. So far out of the limited-time Hololive sushis I've only tried Gigi's "Salmon & Tamago Spicy Roll" and it was very good, my mom seemed to like Kroni's "Tuna with Avocado Cream Cheese." I hope they consider keeping the limited flavors around since they are very good. If you're able to check this place out I'd very much recommend it!
