“Please! Please go out with Kusuri!!! Kusuri loves you too much!!! She super loves you!!! She loves you as much as she loves drugs!!! She'll listen to whatever you say!!!...So, please!!! Well!!!?” Kusuri is energetic and ingenious though has some childish aspects to her enthusiasm, especially in her manner of speech. Her main passion is creating drugs, each with unique, yet often absurd effects. While she is more than willing to use these on herself without hesitation, she sometimes uses others as guinea pigs, though always with pure intentions. Her family all have similar verbal tics in how they end their sentences. She ends her sentences with "-nanoda" ("yep, yep" in the official translation and dub), a childish variation the tic. Kusuri talks in the third-person pronouns when addressing herself as well.
