Setsuna Yashiro

Setsuna Yashiro is a member of Anthos*. His image color is white.

Personality
He has its own unique aura, is mysterious and goes his own pace. Setsuna often sleeps, and he is not interested in anything other than what he is interested in. However, when he is on stage or at work, he can get very concentrated.

Yuki Mahiro
Setsuna is seemingly very fond of Mahiro, as he was the first to teach him about the idol world as well as helping him befriend the entire unit of Anthos* back when he was first introduced as a member who will debut with them.

It is said by Setsuna himself that he thinks that Mahiro is very kind, and he likes him a lot.

Kisaragi Kaoru
Kaoru is also close to Setsuna, seeing that he actually chatted with him about Mahiro in Project Archive A 2-5. Kaoru also did not avoid Setsuna as much as the older brother team (Ryoga, Chise, Lihito) did, as per the archives.

Toudo Lihito
Setsuna and Lihito's relationship had a rough start, seeing that in the end of Project Archive A 2-5, when Lihito finally gained consciousness, he jumped right at Setsuna and claimed that Setsuna did "something" to him and Chise, and sworn that he will never forgive him for it.

Kagekawa Ryoga
At the beginning, Ryoga did not trust Setsuna as easy as Mahiro and Kaoru, and he stayed cautious with him throughout the entirety of the 5 drama tracks. However, their relationship seem to have somewhat mellowed when Ryoga later took Setsuna outside to go shopping and taught him about the concept of buying things, though he refused Setsuna's request of wanting to buy a tree that they saw on the road.
