Inkwell Isle Conference

"Martha Andersson has been organizing the Inkwell Isle Conference right now since the Grand Alliance, the Beleninsk Pact and the New Central Powers would try to drop their weapons and clear off the side effects of How I Can Help Make the World Great so we can get a chance to defeat the truest culprits of the USRAC War; the Belkan Grey Men, the ISIS and the Global Liberation Union. I knew that formal event is just a terrorist-made decoy out there. On second thought, the Grand Alliance, the Beleninsk Pact and the New Central Powers would come together not only for this war, but also for all the future conflicts in World War III in order to restore the peace that we all lost, even non-Rubyism. We'll try to put the real culprits down for good..."

--Su Ji-Hoon, Osea's Peace

In during the half-final of USRAC War after The Journey Home song spread on all of the Inkwell Isle, Cuphead and all of his friends operated and held the Inkwell Isle Conference (also known as the Inkwell Isle Summit) - the great conference between Cuphead and all of his friends with the Grand Alliance, the Beleninsk Pact, and the New Central Powers.

Only happened in during the Harling-Nikanor Conference that the Inkwell Isle would be happened and being spread by The Journey Home song. However, it would be made Cuphead and all of his friends with the Grand Alliance, the Beleninsk Pact, and the New Central Powers that it would be made the peaceful of non-Rubyism and Inkwell Isle.

Also, it would made them against the true culprit of USRAC War - the Belkan Grey Men and the Islamic State of Iraq and Syria, including the rest of the Global Liberation Union in during the Rubyist Cold War

This one is also in collaboration of all the Inkwell Isle countries.
