Yaiba episode 1 highlights

Yaiba episode 1 started off with Yaiba and a bamboo sword in the middle of the jungle. Yaiba was doing so under the instructions from his father, Kenjuurou Kurogane, with the intention of luring and fighting a gorilla to improve his swordsmanship. Although Yaiba didn't have faith in the luring method, a gorilla soon appeared and engaged Yaiba in combat.
Yaiba managed to easily outclass the gorilla with his instincts alone, marking yet another milestone in his swordsmanship journey. Unfortunately, an entire band of gorillas soon appeared, compelling Yaiba and Kenjuurou to escape atop their pet tiger, Kagetora. All three of them managed to shake off the pursuing gorillas by hiding in a banana crate.

Their bad luck continued as the crate got sealed and shipped off to Japan. Yaiba episode 1 then shifted to Sayaka Mine receiving her father, Raizou Mine, at the airport. Sayaka congratulated him for winning the Asia Kendo Championship, an achievement that Raizou didn't pay much heed to since fighting Kenjuurou Kurogane and defeating him would be Raizou's greatest achievement.
Coincidentally, Kenjuurou and Yaiba ended up at the same airport, where Kenjuurou spotted Raizou and dragged him and his daughter, alongside Yaiba, all the way to Raizou's residence. Kenjuurou asked Raizou to look after Yaiba, a proposition that he promptly rejected.
Kenjuurou then went on to arrange a sparring session between Raizou's best kendo disciple and Yaiba to display Yaiba's swordsmanship talent. Needless to say, Yaiba easily overwhelmed the disciple, becoming a part of Raizou's household. Raizou then commented on how Kenjuurou too shall settle down at his age. Kenjuurou rejected the idea, stating how confines and constraints didn't suit him.

The next day, Raizou found out that Kenjuurou simply left the house, leaving Yaiba behind in his care. Yaiba eventually accompanied Sayaka to her school. Sayaka scared Yaiba, mentioning how the school was full of strong monsters who could defeat Yaiba. Although scared, Yaiba said that Sayaka didn't need to worry about anything since he would save her from any such monsters, igniting slightly romantic feelings in Sayaka.
Upon reaching the school's kendo dojo, Yaiba found himself facing Onimaru, the national kendo champion. Although Yaiba attempted to catch Onimaru with a sneak attack, Onimaru easily disarmed him, establishing his actual swordsmanship prowess. The episode ended with Yaiba acknowledging Onimaru's strength, beginning their rivalry, while Sayaka tried to keep the situation from worsening.
Final Thoughts
Yaiba episode 1 served as the perfect introduction to the character while simultaneously establishing the family dynamics alongside Yaiba and Onimaru's rivalry. Yaiba episode 2 will be released on April 12, 2025, and will focus on Yaiba's induction into school.
