Sango could also take care of Kagome. As a strong and kind - hearted woman, she would know how to nurse Kagome back to health. She might use her knowledge of herbs and remedies to make Kagome feel better. Plus, she would offer emotional support to Kagome during her illness.
Kilala, Sango's cat - demon companion, could also play a role in taking care of Kagome. Kilala could provide warmth to Kagome when she is shivering from the fever. And in a more magical sense, Kilala's presence might have some sort of calming effect on Kagome, which could aid in her recovery.
Well, perhaps in the fanfiction, Kagome's sickness is a result of some dark magic. Her getting sick could be a part of an enemy's plan to stop her from interfering in their evil deeds. Her friends then have to not only deal with her illness but also figure out who is behind it all and stop them before it's too late.
Inuyasha may become uncharacteristically gentle. He'll softly speak to Kagome, asking how she feels. His actions are driven by his deep - seated feelings for her. He might even share some of his own insecurities with her while she's sick, like how scared he is of losing her. He'll also be on high alert for any danger, ready to defend her at a moment's notice.
His teammates, Sasuke and Sakura, would surely be involved. Sasuke, although he may not show it as much, still cares about Naruto. He would keep an eye on Naruto's condition, and if there was any sign of danger, he would be ready to protect him. Sakura would be more hands - on with the medical care, checking his temperature, giving him medicine, and making sure he rests properly.
Alfred would probably be the first one to take care of him. He's always there for Batman.
Thor could be one of the first to take care of Loki. Despite their differences, Thor still cares about his brother. He would use his strength to protect Loki from any threats while Loki is sick and might even search for rare remedies.
His best friend could be the one to take care of him. This friend would stay by his side, make sure he takes his medicine on time, and keep him company while he's sick.
Gwen could also take care of Ben. As his cousin, she would be worried about him. She might use her magic to try and ease his symptoms or find a cure. She would probably make him some soup and keep him company while he's sick.
Her friends could take care of her. For instance, Yuki might bring her some herbal tea that he made himself, believing it would help with her illness.
In addition to his family and friends, the medical ninja in the village would be involved. They would be the ones to accurately diagnose Boruto's condition. Shizune, for example, could come and check on him, using her vast medical knowledge. And the other young medical ninjas might learn from this case, as Boruto's illness could be something new or unusual, so they would be eager to assist and gain experience while taking care of him.
One idea could be that their relationship starts as an unexpected alliance against a common enemy. As they spend more time together, they gradually develop feelings. When Kagome discovers she's pregnant, it could bring a new level of complexity to their relationship. Sesshomaru, being a proud demon, might initially struggle with the idea of impending fatherhood but then grow into a protective and loving partner.
