in contrast to her predecessor who often absconded from work to go fishing, Professor Seiland takes her medical work much more seriously. She expresses frustration at the existence of mystical powers which heal others, saying one hand how she should feel rejoiced about Shizuku MacLaine's miraculous eyesight recovery, but mixed feelings on the other and how she doesn't like losing to such things as a medical practitioner, calling it it 'the stubbornness of the medical profession'. She claims to have great ambition for the doctors of the future, stating, 'To perform their work quickly and flawlessly. ...I want the young doctors be like that in the future.'
She is a rational thinker, summarizing that the most likely solution for the transformations induced by red Gnosis is mass hallucination, and expressing her limits of explaining the effect of Gnosis on biochemistry.
