Tenka Ichii!! by Pinku Aomata Tora feels out of place in her highschool with her manly name and rigid dojo upbringing. But she'll find her self more out of place when she slips back into the warring states period. Maybe she'll fit in as she disguises herself a man. Okay so I just based this from the few free pages of Jmanga preview. Based on the preview too I can say it's PG 18 but I'm not sure with the pages ahead. I really want to read this.I love the word timeslip. Gonna create "timeslip" tag for Fushigi Yugi etc. This will be applicable too to parallel universes, different worlds and dimensions.Also, I spy the obligatory twins in the cover.
