Kashin Koji - The Face Behind the Mask
Let's get to know our character first.
Kashin Koji is a character from Boruto: Naruto Next Generations series, Naruto's ongoing series. We haven't seen him in the anime yet, but he's already seen in manga.
Kashin Koji came up with a large frog from Myoboku mountain in the match of Boruto and Ao with the Kuchiyose No Jutsu (Summoning Technique) technique. In the following minutes, this mysterious character, Sarutobi Hiruzen's grandson, also started to fight with Sarutobi Konohamaru, the Sensei of Boruto.
We have read / seen that Konohamaru has learned from Naruto and Naruto has learned from Jiraiya Sensei, using the Rasengan technique as an advantage against Kashin Koji, and that Kashin Koji has also responded to Konohamaru with Rasengan technique.
To summarize ...
In Kashin Koji's Kuchiyose No Jutsu (Summoning Technique), we have seen that he can summon the Frog and use the Rasengan technique.
In addition, according to the black and white structure of manga, Kashin Koji's hair and beards are white.
Now, by compiling this information, let's remember if there was a character in accordance with these definitions in all series of Naruto.
* Can use Rasengan
* White hair
* Someone from Mt. Myoboku has a deal with the Frog.
Maybe if Hatake Kakashi could call a frog, another suspect would intervene, but it would still be a very distant prediction.
Jiraiya Sensei, because it is possible that it is Kashin Koji with all of the features we mentioned.
* The white hair style is almost the same as Kashin Koji.
* That technique that only Uncle Ramenci (has not) yet ... Rasengan
* Can Use Frog Recall Technique ...
But we still have a problem. Jiraiya was murdered as a result of the war he entered with Pain, and his corpse was at the bottom of the sea. Didn't we see a dead character on the screens again? We saw it but this is an exception because Kabuto once said, "I couldn't find his body because I couldn't stand the pressure at the bottom of the sea." Perhaps Jiraiya was not at the bottom of the sea, somehow escaped, and we'll see that later.
