In some fanfictions, Minato saves Naruto physically. For example, he might use his teleportation jutsu to appear right in the middle of a fight and whisk Naruto away from danger. In others, he could save Naruto spiritually. He might enter Naruto's mind, like in the fanfic 'Minato's Mind - Saving Mission', and give him the strength and confidence to overcome his inner demons. Sometimes, Minato saves Naruto from a political situation. For instance, in 'Minato and the Hidden Leaf's Politics', he uses his influence and wisdom to protect Naruto from being used as a political pawn.
I don't know the specific name of the Minato manga off the top of my head. It could be related to a particular genre or have some distinctive features that might help identify it.
Sorry, I don't have that information. Usually, such release dates are made public closer to the actual release time. Keep tabs on relevant manga news websites or forums for the most current details.
Well, the length of Minato manga could vary. It might continue for a few more volumes or maybe wrap up sooner depending on how the plot progresses and the popularity among readers.
I'm not sure exactly. You might want to keep an eye on the official announcements from the publisher or the creator's social media for the latest update.
