Watch Spirit of Wonder: China-san no Yuuutsu Online

The now 50 year old Scientific Boys Club decides to built a ship that sails to Mars on the "Ethereal Current" - a thesis of the wife of a club member which claims that the universe is flooded with Ethereal energy. On this stream they travel to Mars in order to prove an old theory about channels on Mars built by Martians, but there is no life. Many years later, when both theories are considered to be nonsense, a Mars expedition discovers a stone with the inscription "Scientific Boys Club 1954".

Three short stories featuring China-san.

Sometime during the late 19th century, a young Asian girl has made a place for herself in a seaside town as the owner and operator of the Tenkai restaurant and boarding house.. Yet "Miss China," as the locals call her, is in the dumps. She's got a Mad Scientist named Breckenridge living upstairs who is chronically late with the rent, and she's pining for Jim, a handsome watchmaker's apprentice whom she mistakenly believes is pursuing the local flower girl. But this isn't our world. It is a world that has the Spirit of Wonder, where every so often, just occasionally mind you, amazing things happen. The Mad Scientist actually has come up with an incredible invention, and Jim has an unbelievable plan to use it to give Miss China the most beautiful ring in all the World.
