I'm not sure exactly how many TPN mangas there are. You might need to check reliable manga databases or the official publisher's information for an accurate count.
Definitely not. TPN is a work of fiction. The author came up with the concepts and storylines independently, without drawing from any true incidents. It's all about creative storytelling and fantasy.
It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
One TPN success story could be about a patient who was unable to eat due to a severe digestive disorder. Through TPN, they received all the necessary nutrients. Their body started to regain strength, and their overall health improved significantly. They were able to participate in light physical activities again and had more energy throughout the day.
Overall, the ending of the TPN manga brings closure to some storylines while leaving others with room for speculation. The characters' fates and the final resolutions may vary depending on how you view the events throughout the series.
Overall, the ending of the TPN manga is a mix of both expected and unexpected elements. Some characters get the resolutions you might have hoped for, while others face unexpected challenges. It's a bittersweet conclusion that leaves an impact.
