Ultimate Space & Jams Arc
Naomasa is seen outside Yuuei, checking the status of Class 1-A and determines that everyone (except Izuku) is unharmed. He then tells Class 1-A to head back to their class. Tsuyu asks him the condition of Shouta, to which he replies that he is in a critical state but not life-threatening and says that although No. 13 and All Might are injured, they are not in a critical state and are being treated by Recovery Girl. Naomasa then asks Mr Principal whether he can investigate Yuuei to which he allows.

Naomasa then visits Yuuei's Nurse Office, friendly greeting All Might. All Might asks him about the status of the students as well as No. 13 and Shouta, to which Naomasa states that the students are fine and the teachers are not in life-threatening danger. He then says that if he, No. 13 and Shouta had not fought the villains, the kids would probably be in a terrible condition, but All Might says that the students also fought bravely and made those villains look like fools and concludes that they will make fine heroes which Naomasa smiles to.

Sports Festival Arc
Naomasa is seen in a meeting with Yuuei's staff, telling them that he has investigated the villains Shigaraki and Black Mist but could not find any information about them. He then says that they captured and arrested 72 villains at the USJ and says that they were all third rate thugs, however, the problem was that all of them seemingly swore allegiance to Shigaraki. Naomasa insinuates that in an age filled to the brim with heroes, villains must have felt pressurized and that is why they decided to follow Shigaraki's "innocent" simple-minded brand of evil. Naomasa says that he is going to assist in enlarging the police force so that they can continue capturing more criminals.

All Might
Naomasa knows about All Might's condition and is a good friend of All Might.
