Mei and Tenya do not interact all too often due to Mei’s lack of screen-time. However, they share a plentiful number of moments during the Sports Festival, and a few outside.
The two meet during the Sports Festival Arc while they were competing with each other in the Calvary battle while they were on different teams with Tenya on Shoto's team and Mei on Izuku's team. During the Calvary Battle a few teams competed with each other for Izuku's 10 million point headband. After the Calvary battle the two faced off in the Battle Tournament. Before the two faced up, Mei had an idea of her own. So came up to Tenya and gave him one of her gadgets that she calls her babies. Mei let Tenya have one of her support items called the Auto Balancers. Which he wore for his match in the tournament, when the match started. At some point in the match she has demerited the support item through a speaker from one of her "babies" later she showed off more of her another one of her "babies" and avoid fighting Tenya.
After the auto balancer got hard for Tenya to control she later use another one of "babies" called the hover soles. Shortly after landing she used a capture item called the Capture Gun and caught Tenya in the a net. Later she should off more and more of her "babies" during the match. Later after she finished showing off more of her "babies" she walked out of bounds, making Tenya the winner. Tenya got really mad about that and was telling her that she made him look like a fool. He couldn't believe that she took advantage of his noble nature. Since than Tenya has had a huge disliking to Mei for using him for advising on him.
The two would later meet again for costume upgrades for there Ultimate Moves. Mei forgotten Izuku, Ochaco, and Tenya's names and dismissed them. At the Development Studio while requesting for upgrades Mei didn't stop to hesitate to use her inventions on them without their permission. After Mei used a robotic suit that nearly twisted Izuku, Tenya tried to sneakily tell Power Loader if he could improve the cooling devices in his legs. Mei overheard that and put rocket boosters on his arms. After she actives the booster it sent Tenya to the celling. Afterward when Tenya was back on the ground. Tenya told her that his quirk was in his legs as he called her a "mad woman". Mei said the idea was brilliant if he wanted to cool his legs he should run with his arms. Later when Izuku got the idea to start kicking for his Ultimate Move after his arms became unstable do to an injury from a villain. She later told Izuku is he's gonna use his legs he would have to a speed type than a power type hero. She later pointed at Tenya said that he's like armored tank with an F-1 engine.
