Kawaki & Himawari Academy Arc
Upon starting at the Academy, Eiki quickly states his goals on becoming a ninja, making a good impression on everyone. When he dropped his handkerchief, Kae returned it to him, and he developed a crush on her. When Kawaki, older than any other student in the class, tried to befriend her, Eiki found him suspicious and was jealous. He attempted to force a spar against Kawaki, but he nonchalantly dodged all of Eiki's attacks. While having his injuries tended to, Eiki overheard the teachers talking about the tools storage room, and sneaked in, taking a summoning scroll. When he found Kawaki talking to Kae in a secluded spot, he attacked Kawaki with the summon, but was knocked unconscious by the summon, with whom he had no contract. Kawaki defeated it, and he and Kae left him there, certain he'd wake up with no lasting damage.

Without proper recollection of what happened, he continued to distrust Kawaki. He attended Kae's tea party, where he continued to voice his suspicion of Kawaki, even more so upon his awkward answers to questions. When Kae served the cake she made, Kawaki rushed to stop her from eating it, knocking tables over, and covering Eiki in cake. He began hurling plates at Kawaki in retaliation until Kae told them both to stop. Eiki later called out Osuka on her overbearing mocking of Kae. When Kawaki and Himawari exposed Osaka as having forced Neon to go along in lacing the cake with mustard as a prank, Kae dropped her composed attitude to reprimand her for it. When she tried to recompose herself, Eiki and the others were pleased with her genuine attitude. The party resumed, with Kawaki bringing everyone taiyaki.
