Tell her directly how much her help means to you. A simple 'Thank you, sis. You're really helpful' can go a long way.
Just tell her you're interested. For example, say 'Honey, I heard you love your sister's pet stories. I'd love to hear some too.'
Tell her that there are no limits to her imagination when making stories. Encourage her to combine different things she has seen or experienced, like the animals in the zoo and the characters in fairy tales. And praise her efforts and the unique parts of her stories every time.
Create a good study environment for her at home. Make sure there is a quiet and well - lit place for her to study. Also, provide necessary study tools like textbooks and stationery.
Maybe find some non - light - novel books that have similar themes. If she likes fantasy in light novels, there are great epic fantasies in the regular book world.

She can lead by example. If the older sister is active herself, like going for a jog or doing yoga regularly, the younger sister may be inspired to do the same.
Help her organize her study space so she can focus better. When explaining the problems, encourage her to ask questions.

Share your favorite ways of playing with the toys. Maybe you like to line up your action figures in a certain order or create a little town with your toy cars and houses. By sharing your enthusiasm, she'll be more likely to have positive play experiences with your toys.
You could buy her more interesting kanji light novels as rewards. That would keep her motivated to keep reading and thus improve.

You can start by encouraging her to think about things she loves, like her favorite animals or places. For example, if she loves dogs, she could write a story about a magical dog. Then, help her create an outline with a beginning, middle and end.
