Ep 17. Protect the Name! Attack of the Dojo Challengers!

As the episode begins, Kenichi is training with his masters in the dojo as usual. Suddenly, a group of strangers burst into the dojo, claiming to be the "Kowamizu Four". They challenge the masters of Ryozanpaku to battle in the dojo, with the intention of proving that they are the superior dojo. Kenichi and the masters are hesitant to engage in this challenge, but they ultimately agree to defend their reputation.

The Kowamizu Four are all skilled martial artists, and they each have their own unique fighting style. Kenichi and the other masters of Ryozanpaku must work together in order to defeat them. The first challenger is a young girl named Kisara, who uses a swift and deadly style of leg-based attacks. Kenichi initially struggles against her, but he is eventually able to outmaneuver her and strike a decisive blow.

The second challenger is a massive man named Kirikaze, who relies on brute strength to overpower his opponents. The masters of Ryozanpaku struggle to land any significant hits on him, as he absorbs their attacks with ease. However, Kenichi notices a weakness in Kirikaze's defenses, and he is able to exploit it to knock him down.

The third challenger is a mysterious woman named Shougo, who uses a deceptive and dodgy fighting style. She confounds the masters of Ryozanpaku with her quick movements and unpredictable strikes. Kenichi is able to hold his own against her for a while, but he eventually falls victim to one of her traps.

The final challenger is a charismatic man named Ryuuto, who is the leader of the Kowamizu Four. Ryuuto has an impressive combination of speed, strength, and technique, and he is able to hold his own against all of the masters of Ryozanpaku. Kenichi engages him in a fierce battle, and the two fighters seem evenly matched. However, Kenichi is ultimately able to gain the upper hand with a well-timed counterattack.

Despite their victory, the masters of Ryozanpaku are left feeling somewhat uneasy. They know that there are many other dojos out there who are just as skilled, if not more so, than the Kowamizu Four. Kenichi and the others vow to continue training and improving, so that they will be prepared for any challengers who may come their way in the future.

Overall, this episode of Kenichi is packed with intense martial arts action and exciting fights. The Kowamizu Four are formidable opponents, and it takes all of the skill and teamwork of the masters of Ryozanpaku to overcome them. Fans of the series will no doubt enjoy watching Kenichi and his friends face off against these challengers, and the episode sets up some interesting potential storylines for future episodes.
