Would it be possible to have shiai tokens transferred from an alternate account if you have proof that you created and own the account.

Well if you post on the thread with both accounts saying that you own it, you may be able to trade them in to get an item, but, I'm not entirely sure.

And also mine can someone help me in my main/original account i got 4 shiai tokens and in my other account i got 2 shiai token but i cant send the shiai token to my main acc. so do i rly need to say to gm? that can send shiai tokens? to another acc.? alt only not strange names i mean players

no

the shiai tokens are items send them by items sending green

ST are non tradeable, non transferable and are only to be exchanged for the items.
That's the policy, changing it will take too much useless effort. If you don't want to end up with ST on two accounts you own, stop entering GM events on your alts.
