This is a theory about Keikenchi after learning about part of FGOM18.

I desperately need help if anyone can provide information about Shinsaku Takasugi, because it has a affection to my theory.

When I finished reading Oda Nobukatsu and Yamanami Keisuke’s Profile, they all have one thing in common

“Normally he would never have been summonable as a Heroic Spirit”

“Normally, Mañjusaka would cause Nobukatsu's entire Saint Graph to disperse”

“However, he ultimately realized this was still proof of his weakness, so he entrusted his affairs to his companions and was eventually destroyed. That was how it should have been, but in the Shin Yamatai-koku, he returned from hell.”

Yes, that’s the feel that "their story should have ended there, but was forced to change its course because of the readers' desires."

Remember what Nasu said about Artoria, ”Her story is end, so I don’t want her have any appearance in the future.”

I’m afraid that Keikenchi is thinking the same thing, because Yamanami Keisuke’s Profile was like telling me, "You readers forced me to do this."

If you want Gudaguda’s NPC, then convince or force Keikenchi, because he doesn’t want to.
