>Lilly
An arch. I know its not a shape per say but i think it suits her elegant nature.
>Hanako
Circle. Stands out for having no corners but makes her approachable if done right. Also an allegory for easy headpats.
>Shizune
Triangle, sharp and aggressive looking but the most optimal and recognizable.
>Misha
Enneagram. Really stands out and attracts attention one way or another.
