A youthful railway manga! It’s name is 『Yuri-Tetsu』! A all-girls high school railway club enters the stage! With four beautiful train-loving girls, get ready to be lured by railway travels!! This time’s trip, 「Traveling Hotel」, or as many fans call it, the 『Hokutousei 』, travels to the northernmost region, Sapporo! Everybody, let’s look forward to boarding!!

It follows the adventures of a male (who seems to change every few chapters) and a short, humorous, but mostly ecchi encounter with the various females he meets, whether it's in school, in the class room, or in the nurse's office.

The story is set in the near future when the marriageable age was lowered in response to the declining birth rate. A 24-year-old man marries a 12-year-old girl in this gag comedy.

Zashono Academy is unique in all the world. It has 54,000 students and this allows for some VERY specialized clubs. There are clubs for just about everything you can think of... and then there's the Eiken club. No one seems to know just what it's about, but they do know that it's filled with some of the most bodacious babes ever to be brought together! ...and then there's Densuke. Densuke is a little awkward and clumsy and he always seems to be in the most compromising positions with all the other club members. And all he really wants is to be with the cutest girl on campus, the lovely Chiharu. Will he ever be able to get away from the uncomfortable club activities and let Chiharu know what's really on his mind?
