The Senpai King II: Senpai's Pride

The film opens a few months after the events of the first film where Kale gathers the animals of the Pride Lands together for the presentation of King Senpai and Queen Monika's new daughter Yumi, with Pico's spirit proudly watching over the ceremony.

Months later, Senpai becomes very overprotective of young Yumi, assigning Diego and EmperorDaFirst to be her babysitters. One day, while Diego and EmperorDaFirst are distracted because they're arguing over their lunchtime, Yumi sneaks into the Outlands where she meets a young cub named Hex. After escaping a river filled with crocodiles, the two become friends, but Senpai and Hex's mother, Sky, quickly end their playtime by roaring at each other. Sky claims that the Pride Lands belonged to Sunimal, But Senpai reminds her that he banished her and her group of lions called the Outsiders because of it. Sky then reminded him that Hex is Sunimal's hand-chosen successor. Unwilling to harm the cub, Senpai orders them to leave and later scolds Yumi for endangering herself and reminds her role as future queen. In the Outlands, Sky's eldest son, Raymond, complains to his younger sister Sarv, about Hex's status as "the Chosen One" despite not being Sunimal's real son. At that moment, Sky returns and rebukes both of her sons, but then decides that she can use Hax's new friendship with Yumi to get her revenge against Yumi.

Years later, Kale becomes worried about what to do now that Hex has grown up, becomes stronger, and is following Sky’s orders to destroy Senpai and the Pride Lands. But Pico, using the wind to communicate, encourages him to reunite the Pridelanders and Outsiders together through Yumi and Hex. At first, Kale is hesitant but eventually decides to trust Pico on this. A few days later, an adolescent Yumi heads out to do her first solo hunt. However, Senpai is worried and fearful of his daughter unprotected and sends Diego and EmperorDaFirst to watch her again, despite promising not to. Furious to find out her father lied to her, Yumi decides to hunt away from the Pride Lands, though is still unsuccessful in her efforts. Raymond and Sarv set fire to the plains where Yumi is hunting, causing her to faint and give Hex the chance to rescue her, as part of Sky's plan. Drawn by the smoke, Senpai and Monika find them together and Senpai ungratefully repays Hex his debt by allowing him to come to Pride Rock, though he is ordered to sleep outside the den. That same night, Senpai has a nightmare about his father's death, only in the dream, Sunimal morphs into Hex and throws the panicked and frightened Senpai off the cliff into the stampede.

The next day, Senpai walks outside the den to drink at a watering hole where Hex contemplates attacking him. However, Yumi interrupts and they go off together so Hex can help her learn to hunt. During the lesson, they run into Diego and EmperorDaFirst struggling with some birds, so the two lions help them chase the birds off. Together, they have fun playing, something Hex notes he has never experienced before. From this point, Yumi and Hex grows closer. That night, Hex tells Yumi that he is not Sunimal's real son, but feels that he's still a part of him and fears he may have the same darkness as Sunimal had. Senpai, who is hesitant to trust the young Outlander around his daughter, seeks guidance from the "Great Kings" and Monika gently advises him to give Hex a chance. Hex decides to leave after trying to confess his real intentions, but Rafiki stops and invites the young lions to experience "Upendi" – which means love in Swahili. After a musical journey through the jungle, the two fall deeply in love. Senpai finally warms up to Hex and invites him into the den to sleep. Unbeknownst to them, Sarv observes them and alerts Sky of Hex's "treachery".

In the morning, Senpai invites Hex for a walk and tells him the true story of Sunimal, which Hex had never heard before. However, their walk is interrupted by Sky and her pride. After Sky deceitfully praises Hex for leading Senpai away from his pride, Senpai believes that Hex had set him up. Hex *truthfully* claims he had nothing to do with it, but Senpai is distrustful. After a brief fight, Senpai manages to escape by scaling a wall of logs in a gorge. Unfortunately, in chasing after him, Raymond slips and is killed by falling logs. Sky blames Hex for Raymond's death and angrily strikes him in the face, leaving a scar over his left eye, similar to Sunimal's, and calls him out for "betraying" his pride, Sunimal and "killing" his own brother. Finally fed up, Hex leaves, and Sky tells the Outsiders that Senpai has corrupted Hex, and they must take the Pride Lands by force. Hex returns to the Pride Lands and begs the king for his forgiveness. Still believing Hex was behind the ambush, the distrustful Senpai exiles him and strictly orders Yumi to be confined in Pride Rock and forbids her to leave unescorted. This angers Yumi, who scolds her father for not seeing Hex for who he is, leading her to escape from the den to find Hex. After a long search, she reunites with Hex. Upon watching her and Hex's reflections complementing each other's, Yumi realizes the meaning of what her father told her when she was a cub, that "[they] are one". Realizing what they must do, Hex and Yumi return to reunite their prides.

Meanwhile, Sky leads her pride in a war against the Pride Lands, and a fierce fight breaks out. As Sky and Senpai face-off, Hex and Yumi leap between them, and Yumi tells her father that the fighting has to stop, reminding what he once said to her that they are one, pointing out that the Outsiders are also part of them. Yumi's words manage to sway Senpai and the rest of the pride, but Sky refuses to stop fighting. Finally, when Sarv decides to side with Yumi and Sky tells her daughter that she will die too if she does not fight, the other Outlanders, shocked and disgusted by this threat, turn against her and join Senpais side. Still unwilling to let go of her hatred, Sky makes one last attempt to kill Senpai by leaping at him, but Yumi pushes her away, and they fall over a cliff. Senpai safely lands on a ledge, but Sky is sliding towards a storm-swollen river. Yumi offers to help, but Sky, like Sunimal, cannot let go of her hate and falls to her death. Senpai helps his daughter back up the cliff and allows the Outsiders, including Hex, to return to the Pride Lands. Additionally, Hex marries Yumi before joining her and her parents at the top of Pride Rock, roaring at the cheering animals. Pico's spirit proudly watches over from among the stars and praises his son for his decision.
