Lumia Island is controlled by a central computer system centered on a research center.

If you put together several components such as a broken laptop, a mobile phone, and ion batteries, you can turn on the network PC and cause the system to malfunction and remove the restricted area. Characters with knowledge like JP can easily do it, but if they are caught trying to hack hastily, they can be killed by the researchers.

After successful hacking, if you get the secret code that only Mr. Meiji can manipulate, you can access to the central computer and explode the bracelets of all the other participants.
