One possible plot could be that the mama, who is a student, discovers she has some hidden ninja abilities related to Naruto's world while studying. Maybe she's studying something related to history or mythology and it turns out to be real in the Naruto universe.
Perhaps the mama, as a student, meets a character from Naruto in an unexpected way. For example, she could be doing an internship at a research facility and Naruto or one of his friends shows up because they are on a mission related to the place. Then, she gets drawn into their adventures while still trying to balance her student life.
I'm not sure about a specific 'mama is a student naruto fanfic'. But you can try searching on fanfic websites like FanFiction.net or Archive of Our Own. They have a vast collection of Naruto fanfics and you might find one that fits this concept.
A possible plot in a 'death of naruto fanfic' is that Naruto is killed in a political conspiracy within the ninja world. This could lead to a war between different ninja clans as they try to figure out who is responsible. Or perhaps Naruto's death is the result of a time - traveling enemy who changes the past in a way that Naruto no longer exists, and the story could be about his friends trying to reverse this change.
Well, perhaps the plot could revolve around Naruto being lazy in his ninja training. As a result, he starts to fall behind his peers. This causes some conflict within the team, like Sasuke getting frustrated with him. Then, Naruto has to find the motivation within himself to catch up. It could also be that a new character enters the story and tries to use Naruto's laziness to their advantage in some way.
A plot could be where an enemy uses the Kubikiribocho to cause chaos and Naruto has to find a way to stop them. He might need to team up with some unexpected allies and figure out the weaknesses of the weapon. He could also try to find a way to sever the bond between the enemy and the Kubikiribocho.
One possible plot is a power - struggle within the Hidden Sand that the Kage of Suna has to deal with, and Naruto gets involved to help maintain peace. For instance, there could be a group within the village that wants to overthrow the Kage, and Naruto uses his talk - no - jutsu to defuse the situation.
A plot could also be centered around Naruto asking Kurenai out on a date. He would be really nervous and might ask for help from his friends. His friends could give him all kinds of advice, some good and some really bad. And when he finally does ask her, Kurenai's reaction could be a mix of surprise and amusement. This could lead to a series of events where they get to know each other better on this 'date' and explore their relationship further.
One possible plot is that Pain targets Hinata to get to Naruto. Since Hinata has a special place in Naruto's heart, Pain might think that by hurting her, he can break Naruto. But Hinata shows great courage and Naruto comes to her rescue.
In this kind of fanfic, a possible plot is that Minato and Naruto get to spend some normal family time together. They could go fishing, like Naruto used to do with Iruka. During this time, they bond and Minato gets to understand the simple joys that Naruto has in life, which he might have missed out on if he were still alive in the normal Naruto storyline.
Maybe the fanfic has a plot where Madara's eyes are actually sentient in a way. They start to communicate with a young and inexperienced ninja. The eyes guide the ninja to become stronger and more powerful, but also lead them down a path that might not be entirely ethical. The ninja then has to decide whether to continue following the eyes' guidance or break free from it.
Another plot could be that a mysterious entity bestows the power of Super Saiyan Blue on Naruto. He then has to keep it a secret from his friends and village while also using it to protect them from a new and powerful enemy. This would create a lot of internal conflict for Naruto as he tries to balance secrecy and heroism.
