'Boruto: Naruto Next Generations' Episode 187 Spoilers: Kashin Koji Is A New Threat

Before Team 7, Katasuke and Konohamaru could rest for a while, a new danger appears in the form of Kashin Koji in "Boruto: Naruto Next Generations" Episode 187.

The official preview trailer for the upcoming episode, which is titled "Karma," shows Koji's battle against Boruto and his friends.

In the trailer, Koji ridicules Ao for his inability to complete this mission. The scene changes to Koji appearing right in front of Konohamaru, who seems to be instructing Boruto and the others to back off.

Whether Konohamaru is the only one taking on Koji is yet to be seen. The final scene of the trailer shows the strange symbols on Boruto's palm. It will be interesting to see if Koji's appearance has activated the seal on Boruto's palm.

"Boruto: Naruto Next Generations" Episode 187 is scheduled to air Sunday. Crunchyroll is streaming the episodes.

Fans can recall that in "Boruto: Naruto Next Generations" Episode 186, Ao manages to locate Boruto's hideout. However, it is a trap as Mitsuki, Konohamaru and Sarada are to attack Ao.

Due to Scientific Ninja Tools, Ao is able to absorb the jutsu and the attacks are nullified. However, Ao realizes the attacks are just diversions as Boruto and Katasuke remain missing from the scene.

Soon, Boruto ambushes Ao and a fierce battle begins. Like Ao, Boruto also utilizes the Scientific Ninja Tool to counter the attacks and open a window for his signature Rasengan attack.

Toward the end of the episode, Boruto defeats Ao and the latter asks him to avenge Mugino's death. However, Boruto spares Ao's life and before they could leave, Koji appears.
