Upon waking up from the dream, Josie traveled from the 21st century to Chicago in 1943, becoming a poor boy wandering the streets.

As an orphan, how he can survive in this age is the most important thing.

Fortunately, he has a plane trading system. In this era, being a master of time and space can make a good life if you think about it.

However, a few months later, Josie, whose life had just improved a little, looked at Captain America, who was singing and dancing with a group of girls on the stage of the war fundraising benefit performance, and fell silent.

It’s over, Barbie Q is over.

This is Marvel!
