Unrequited love is a common theme. Often, characters in the harem have feelings for Naruto that are not reciprocated, leading to sadness. Another theme is sacrifice. Some characters might sacrifice their own happiness for the sake of the group or Naruto, which is really sad.
Well, 'Sorrow in Naruto's Harem' is also quite interesting. In this fanfiction, the harem aspect is combined with sad plotlines. For example, some of the female characters in Naruto's supposed harem have to deal with unrequited love or difficult choices, which leads to a lot of sad and emotional scenes.
Definitely Hinata. Her love for Naruto is well - known. Sakura, too, as she has grown closer to Naruto over the years. Ino might also be in the harem. She has had her own moments with Naruto and her skills as a ninja could be an asset. And perhaps Karui from the Cloud Village. After Naruto's peace - making efforts between the villages, she could have developed feelings for him.
Sakura would be a likely candidate. She has a long - standing relationship with Naruto, so she could be part of the harem. Hinata is also a strong possibility as she has deep feelings for Naruto. And Ino, who has known Naruto for a long time and has her own charm, could also be in the harem.
Sakura could be in Naruto's harem. In the original series, she had a long - standing relationship with Naruto. In this fanfiction, with Naruto being 'dark godlike', she might be drawn to his new power and the mystery surrounding him. Also, Hinata would be a likely candidate. Her long - held feelings for Naruto could intensify with his new status, and she would be part of his harem due to her loyalty and love for him.
Sakura could be in the harem. She has a long - standing relationship with Naruto in the original series, and in this fanfiction, his Saiyan powers might make her see him in a new light. Hinata is also a likely candidate. Her admiration for Naruto could turn into a deeper relationship given his Saiyan - like abilities.
Hinata could be a likely member. She has always had feelings for Naruto. Sakura might also be part of it, as she is an important female character in the Naruto series. And perhaps Tenten, who is strong and independent and could be attracted to Naruto's new winged form.
A Naruto fanfiction can be sad when it delves into the sacrifices Naruto has to make. He gives up so much of his personal life and relationships for the sake of the village and his friends. If a story highlights how he loses his close friends, like Sasuke in some darker interpretations, it can be extremely sad. Additionally, if it shows Naruto being misunderstood by the people he's trying to protect, that also adds a layer of sadness. For instance, if the villagers still don't trust him despite all his efforts, it can be a very tragic situation for Naruto.
In such a fanfiction, Princess Bubblegum from Adventure Time could be in the harem. She's intelligent and powerful, and Naruto's unique skills and personality might attract her. Also, Sakura from Naruto could be part of it. Since she has a history with Naruto and in this crossover, she could be part of the group vying for his attention. And Marceline too. Her cool and edgy nature might be drawn to Naruto's heroic side.
It's not appropriate. The 'Naruto' series has a positive and inspiring theme. Fanfiction with such inappropriate concepts as nudist and harem not only disrespects the original work but also can have a negative impact on the audience, especially younger fans.
