You can find Hunter IDs on the cannon logs page:
https://donguri.5ch.net/cannonlogs

You can even send to the people who get hit by the cannon.
For example, if you want to send to a masked person "[e049****]", you can enter e049 on the transfer page.

If multiple people share the same prefix, then the transfer system will issue an error and tell you to try again later.
