Little is known about Nabeshima aside from his role in Ryuga Banjyou's life. On the orders of Faust, he approached Kasumi Ogura, Ryuga's fiance, and had her direct Ryuga to Takumi Katsuragi in exchange for helping Ryuga make a comeback as a fighter. When Ryuga arrived to meet, he was framed for Katsuragi's murder and placed in prison, where Nabeshima sedated him and brought him to be experimented on by Faust.

When Ryuga finally was able to get ahold of his contact information and call him, Nabeshima revealed to Ryuga that the organization that experimented on him, Sento, and the Smash was called Faust, and that they were holding his family in Seito, saying he would testify against Faust if Ryuga rescued them. However, this information was delivered on Night Rogue's order to lure Ryuga to Seito, Nabeshima expecting his family to be freed by his playing along; instead, his reward for his service was being turned into a Smash himself, the Mirage Smash.
He attacked a group of Touto Guardians and Sento, fighting Build RabbitTank by duplicating himself. After Build switched to HawkGatling and defeated him and all his duplicates, his Smash essence was removed into a blank Full Bottle. However, he was taken away by Blood Stalk after being recognized by Sento. Nabeshima was subjected to Faust's experiments again, transforming into the Square Smash. He was set upon a park, coming to blows with Build once again.
After fighting for some time, Blood Stalk fires upon him with his Steam Rifle, causing him to grow in size. Build proceeds to defeat him with the Full Bullet finisher, and upon having his Smash essence extracted returns to normal once again. Some time later he wakes up in nascita's basement lab, realizing he has no memory whatsoever, even when reunited with his wife and daughter. Shortly after the reunion he goes over to the panel with the Fullbottles plugged in, suddenly remembering that Faust had similar bottles as well.
