Inosuke Hashibara is NOT his name
LN forward states that Tengen canonically NEVER addresses Inosuke by name. Tengen is a white birch, so there is definitely a reason for that. I've shown that they don't associate people with external factors like their looks and instead seem to look at people as "souls" in the spiritual realm (Unseen World). If he's not using Inosuke's name than it means it's NOT INOSUKE'S NAME.
Hashibara Inosuke -- 嘴平 伊之助 -- is NOT a real-world name. It sounds, phonetically, like it could be, but it isn't. In a world where all characters trace their bloodlines back to real-world (or near-real-world) clans and supernatural entities, WHY is Inosuke stuck with a fantasy made-up name? On a surface level it references being a boar, but that's not the point; the point is, WHO ARE THE HASHIBARA. They DON'T EXIST.
I used to think the name on little kid Inosuke's wrapping was Kotoha's husband's name, ie, his legal name. But it's NOT. In the databook entry, the "Father" entry in the family tree is nameless. I knew already that Shinjuro was his biological father so I just glossed over that fact, ie, it's just to hide who his biological father was. BUT I MISSED A CRITICAL POINT: the OTHER reason is that it could be "Hashibara" was simply NOT HIS NAME.
It's a made up name. So WHO made it up? Why like that? I, of course, found the answer:
嘴平 = "Hashibara"
伊 = "I"
之 = "no"
助 = "suke"
In the SAMURAI ADDRESS SYSTEM, it literally means:
"Vice-Commander of Ise Province Hashibara" / "Hashibara I-no-suke". The "I" being the abbreviation for the province / country which was the standard in this address system. -suke just meant "helper", ie, he-who-aids-the-leader.
Ise was unique in that it wasn't the domain any major warlord in the Sengoku, it was made up of independent villages, and their warriors were called "Ji-Samurai" = "Earth Samurai". They were famous for their toughness and specialized in guerilla warfare and mountain terrain fighting ability. They would later become the historic foundation of the Shinobi. When their village leaders and such went to meetings with the major powers they very often took the official names of "-suke" to show their rank in the hierarchy.
And BEFORE the collapse of the Imperial Court and the end of the Heian Period, Ise was home to the Grand Shrine of Ise, the most sacred location in Shintoism. Every year the Imperial Court held grand seasonal festivals there, and one of the most important was.....
KOCHO-NO-MAI, the Butterfly Dance.
Children of nobles would dress up in butterfly wings and flower garlands and dance before the Imperial court. offering the performance to the heavens in a prayer for peace and prosperity.
So....okay. WHO put that name on Inosuke's cloth?
Two options. One is his biological father, Shinjuro. The other is Kokushibo. Both have arguments for and against this, but overall I think Shinjuro is the best candidate. The strip was carefully written with a clear but modern-style using a brush calligraphy and we see Shinjuro writing with a brush as the cover of the VERY NEXT chapter after Inosuke enters battles for the first time in ED against the Obi Demon. We never see Kokushibo write anything, but the Samurai addressing, the use of "boar" imagery in the first name strongly suggests someone FOUND Inosuke like that (with boars) and if it was Kokushibo he could sense his genetics and maybe recognized his old subordinate which may have come from Ise (the Ji-Samurai were very sought after). Furthermore, notice the little boar mask? In Samurai custom names are given in a ceremony where the hat-parent puts a hat on the child symbolizing their new name which is different than what it was as a child. But then the Rengokus go back to the Sengoku at LEAST and the Corps has maintained Samurai customs until it's disbandment so it's not that strange Shinjuro would come up with something like that.
"But didn't Douma say....?"
No, KANAO said. The moment Inosuke has his mask taken, she says his name for the FIRST TIME. She SHOUTS it -- not at Inosuke, he knows his mask is gone. SHE'S SHOUTING IT AT DOUMA.
"HIS NAME IS INOSUKE".
More research is needed to figure out the lineage between Shinobu and Inosuke and WHY this whole identity game is being pulled. He's Shinjuro's biological son, okay, but why hide the LEGAL name? Did Kotoha name him after Shinjuro or something? But I'm glad I've had this breakthrough in the hidden plot.
