Eijiro Kirishima & Rikido Sato vs. Ken Ishiyama is a battle fought between Class 1-A heroes-in-training Eijiro Kirishima & Rikido Sato and Pro Hero Ken Ishiyama during the End of Term Test Arc in the Replica City-District.
While Recovery Girl announced the first team to pass, Eijiro and Rikido were surrounded by Cementoss's walls. Eijiro and Rikido smashed the walls; however, Cementoss created walls faster than the speed at which, Eijiro and Rikido could smash them. Although Rikido was dazed from overuse of his quirk; Eijiro tried to tell Rikido that he needed to continue breaking the walls. Cementoss replied that Eijiro and Rikido are bad at "battles of attrition" and must use their particular strengths. When the time is up, Eijiro and Rikido failed the exam.
Kirishima & Sato lost and were sent to Remedial Class
