Yes. It's true. You'll be able to buy a Mii Gunner costume of Sans in Smash Brothers Ultimate later today! It'll come with a special arrangement of Megalovania composed by me. It's a huge honor to have something I created in Smash. Thank you so much Mr. Sakurai!!!
I wrote more beforehand but I'm so shocked that Sakurai-san talked about our meeting. If he's going to mention me, then I have to tell everyone that we listened to a CD of Smash music as he drove me home in his car (which I kept calling his Batmobile)
