Senshu's Links
Looks up to Suiko for her elegance and wishes greatly that he could have gotten to know her better growing up. He is happy to have her as a sister and tries his best to write letters with the help of their "mother", Litura.
Out of all her litter mates, Senshu is the brother she was most sad about leaving. She always looks forward to receiving his letters and is happy to have maintained a connection with him in writing. She's hopeful for the day they can be reunited in person.
