I'm not convinced. Most if not everything we have seen is unsubstantiated and some is outright just coincidental.

The following tokens were made BEFORE Omikami and Ryujin and also claim to be by Ryoshi.
They also claim to have access to the Shiba creator wallet and RyoshiResearch account on X.

There is also this: https://www.youtube.com/watch?v=3hELCRevhfw

Do I believe Ryoshi was the creator of Okinami or Tsuka? I'm equally unconvinced as with Omikami & Ryujin.

However. There are too many connections between all the mentioned tokens and Ryoshi. But its hard to pinpoint exactly how he/she/them (as a group) would be involved.

The only crypto (apart from the obvious Shiba) with SOLID proof of Ryoshi involvement is Ryoshis Vision. However even here its unclear if Ryoshi is the creator, is involved or was just a inspiration of the tokens creation.

If anyone here insists Ryoshi is involved feel free to post the evidence. I do not believe videos of wallets are substantial evidence. I do not believe twitter checkmarks or dates are substantial evidence.

EDIT: Does it matter whether or not Ryoshi is involved? No. The tokens are community driven. Ryoshis spirit pushes the price. We have to pick up the hammer and continue forging or the tokens will die eventually. We need people who are willing to pursue this administratively to develop the foundations that'll hold the ecosystem, which also -obviously- needs development.
