Let's go on with Nise no Chigiri and our heroine Mana Shiraha! Mana is an average high school student whose life is pretty ordinary. Her life, though, takes a turn for the worse when she happens to travel back in time. She finds herself in the Sengoku Jidai, aka the Warring States Period. At a loss of what to do, she encounters one of the generals, Masatora Uesugi, who decides to protect her from Shingen Takeda, his rival. What will Mana do, knowing the epilogue of the war?

Sora wa Akai Kawa no Hotori and Nise no Chigiri share the main concept: a girl who travels through time and falls in love with someone met in the past.

Let's now move to the small country of Adarshan and its political mischief! The country of Adarshan painstakingly conquered one of the territories of the Castoria Empire.

This political marriage has one big problem, among the others: Justinia is only 10-years-old!

By the premises, Sowa wa Akai Kawa no Hotori and Adarshan no Hanayome may not look similar at all. Yet, scratching the surface a bit, it's easy to see that these two series are both shoujo manga with an historical setting, featuring war, romance and adventure. Our heroines, Yuri and Justinia, are both smart, tenacious and with a tendency toward trouble. These two manga have political schemes, and involve royalty. Consider Adarshan no Hanayome the shorter version of Sora wa Akai Kawa no Hotori, and with a younger protagonist!

Let's end this list with Sengoku Strays! Our protagonist is Kasane, and she is your average girl with one, big passion: kendo. One day, her ordinary life changes for good; a mysterious sword sends her back in time, during the Sengoku Era. Of course, the new environment scares Kasane, who remains at a loss of what to do. If things could be worse for Kasane, she finds herself in the middle of Oda Nobunaga's rise... How will she manage to survive and, finally, get back home?

What about a shounen version of Sora wa Akai Kawa no Hotori? Sengoku Strays is a shounen manga, sharing with Sora wa Akai Kawa no Hotori a historical setting and, of course, the main concept of the time travel. Yuri and Kasane face the exact same situation: they meet a ruler and befriend him, and then get involved in war. Our heroines both become good fighters and strategists, and there's room for romance. Consider Sengoku Strays a shounen version Sora wa Akai, so if you're willing to read something similar to it, but with more action than romance, give it a try!
