Im looking for a manga where the protagonist goes to the past and uses their knowledge of the future or past for their own advantage.
an example would be Nobunaga no Chef

Again!! . Sadly, that's the only one that comes to my mind. no, wait. Ore ga Doutei o Sutetara Shinu Ken ni Tsuite is one of these too. though the main characters don't really take advantage of it. hope you'll enjoy them.

Oda Nobuna no Yabou - this defintily
Bakudan! - Bakumatsu Danshi - not sure yet.

Thanks for the replies
