This page outlines Shiki's relationships with characters in the Senran Kagura series.
Family[]
Shiki's Mother & Father[]
Very little is known of Shiki's parents, but it can be surmised that she had a stable relationship with them due to the fact they more or less spoiled her with money before their deaths.
Friends[]
Akko[]
One of Shiki's friends who appears in name only. Not much is known about her, but Shiki does mention that "she's one rude girl". Shiki also says that Akko isn't quite as rude as Imu, though.
Anna[]
One of Shiki's friends who appears in name only. She's long-winded, but seems to be a decent person.
Harue[]
One of Shiki's friends who appears in name only. Shiki catches the last train to meet Harue at a club, but she is stopped by Ikaruga, who's cracking down on late-night loitering. Shiki never makes it to the club.
Hitomi[]
One of Shiki's friends who appears in name only. Hitomi is apparently very knowledgeable about things, such as the fact that hot-tempered people should take extra calcium. it seems she has a very strong relationship with Shiki who is fond of heart sutra meditation and old-fashioned things.
Meg[]
One of Shiki's friends who appears in name only. She calls Shiki in the middle of the latter's battle with Mirai in Shinovi Versus, but nothing else is known about her.
Mizuho[]
One of Shiki's friends who appears in name only. Supposedly, she'll risk her life to get her hands on new products from her favorite brands.
Yaeko[]
One of Shiki's friends who appears in name only. There's a scene in Shinovi Versus where Shiki receives a call from Yaeko, but she is never seen, so there is no way to determine what kind of friend she is.
Yuria[]
One of Shiki's friends who appears in name only during Mirai's Shinobi Girl's Heart storyline in Shinovi Versus. She visits the Super Sengoku Wars mecca with Shiki, but has already left by the time Mirai shows up. From her actions, one can surmise she's a huge anime fan.
