American Comic Dimensional Trading Device

When Josie woke up from her dream, she found herself transported from the 21st century to Chicago in 1943, becoming a poor street kid.
World War II? For Josie, who was not yet an adult, it was too far away.
As an orphan, the most important thing for him is how to survive in this era.
Fortunately, he has a dimensional trading system. In this era, he can make a good living as a time-traveling reseller.
However, a few months later, Josie, whose life had just improved somewhat, fell silent as she looked at Captain America singing and dancing with a group of girls on the stage of a war fundraising performance.
It's over, Barbie Q.
This is Marvel!
