In this fanfiction, perhaps Ashura Otsutsuki in the mindscape is trying to convey a message about an upcoming threat to the Naruto world. He could be guiding the protagonist to gather certain artifacts or allies to face this threat. For example, he might lead the character to an ancient temple where a powerful weapon lies, which is crucial to defeat the new enemy.
He might interact with Naruto himself. Ashura could act as a mentor, guiding Naruto on how to better control his own chakra. Since Naruto has the power of the Nine - Tails, Ashura could show him ways to merge his own chakra with the Nine - Tails' chakra more effectively, enhancing Naruto's power.
One possibility is that Asura Otsutsuki could impart some ancient knowledge or power to Naruto. Maybe he reveals secrets about the Otsutsuki clan that could help Naruto in his battles or in understanding the world better.
One possible plot could be that Naruto discovers he has Otsutsuki blood in him. This could lead to him having new and uncontrollable powers that he has to learn to master. He might be shunned by some in Konoha who fear his newfound abilities, while others see it as an opportunity for Konoha to become even stronger. Naruto would then have to struggle with his identity and prove that he is still the same Naruto they know and love.
She might encounter Naruto's hidden fears and help him face them. Maybe she'll discover memories Naruto has forgotten or suppressed.
It could be that Naruto's awakening of Ashura is a gradual process in the fanfiction. At first, he might experience strange visions or dreams. As it progresses, he starts to notice changes in his chakra flow. Eventually, when the full awakening occurs, he gains not only power but also a new sense of purpose. He realizes that he has a greater role to play in the grand scheme of things, not just for Konoha but for the entire ninja world. He might then start to train others to prepare them for future threats, using the knowledge and power he gained from awakening Ashura.
Naruto's personality might become more serious. Since Asura Otsutsuki is from an ancient and powerful clan, his influence could make Naruto more aware of the greater responsibilities and the bigger picture in the ninja world.
One possible plot could be that Naruto discovers he has some hidden Otsutsuki bloodline. This leads to him being ostracized by some in the village who fear his new - found power. He then has to go on a journey to learn about his Otsutsuki heritage, facing challenges along the way and also having to prove that he's still the same Naruto at heart.
Another plot twist could be that Kaguya kidnaps Naruto to use his connection to the Nine - Tails. She might be trying to gain control over the Nine - Tails' power for herself. But Naruto, being the resilient character he is, manages to resist her control and instead starts to influence Kaguya. He might make her see the error of her ways or at least make her question her motives.
One possible plotline could be Naruto exploring his parents' memories in the mindscape. He might discover secrets about their past, like how they met or their early days as shinobi. For example, he could find out about his father's training and how his mother came to be a jinchuriki. This could lead to Naruto gaining new powers or a deeper understanding of his heritage.
Well, in this fanfic, the plot could involve Minato using the mindscape to help Naruto deal with his inner demons. Naruto has always had self - doubt and insecurities. Minato could train Naruto to face these head - on by creating scenarios in the mindscape. He could also teach Naruto some of his signature jutsu, like the Rasengan, but with a new twist that only the mindscape training can offer.
