Rants/Quips

Sen is naturally quite quiet and reserved, but in battle will taunt, jest, rant or convince depending on who she's fighting and what she thinks will work. She's usually quite diplomatic but can easily be mischievous and goading when she needs to be. She's an incredible liar and can - and does - bullshit all the time to throw people off.
Hobbies
https://desuarchive.org/tg/thread/92275249/#92278175
Academics. Sen was in Shimogakure's university for philosophy and psychology in particular. Her lack of confidence and current state of mind have had her drop her studies - she'd like to get back to them but can never find the energy.

Upper right arm.
Spare Scrolls What Do

Give them to a team that needs them.
Crush
https://desuarchive.org/tg/thread/92398134/#92400321
Sen is too old for most of the cast. She might have some brief feelings for some of the older kunoichi like Himari, Choko and Rinka but nothing resembling a crush and she's not looking for romance.
Sleep
https://desuarchive.org/tg/thread/92406359/#92407096
She always has trouble sleeping due to her current mindset. She normally relies on medicine or self-inflicted Genjutsu to sleep and inevitably wakes up when it runs out, usually gets about 4-5 hours.

Birthday Presents
https://desuarchive.org/tg/thread/92498234/#92503152
Tsugumi - Sen would feel too embarrassed giving Tsugumi gifts, especially when she knows it can't be a surprise.
Junki - A little hand-made (badly) token of the bird. Also whatever he's secretly been looking at over the past few months - She Knows.
Ghidorah - A hand-made (badly) token of Tock. Also whatever he's secretly been looking at over the past few months - She Knows.
Kage
https://desuarchive.org/tg/thread/92548599/#92553280
Professionally respectful and nothing more. Sen doesn't have a particularly fond view of the Kage and believes they're largely responsible for the current state of the world. She does recognize their strength, skill and that many of them are trying, however - and realizes her voice isn't loud or important enough to change anything.
War Experience
https://desuarchive.org/tg/thread/92548599/#92555706
Team Chiyoko (Sen, Kitsumoto, Aoki) were an active Genin team for pretty much the entirety of the war, but as Genin of Shimogakure didn't see a lot of direct conflict. Mostly acted as spies, bodyguards, recon, etc. Operation Tragic Backstory was the moment the war really caught up with them, where they lost their Jonin and Aoki - Sen and Kitsumoto were then separated. It's a long story, but the war started comparatively kind to Sen and then went very, very wrong towards the end.
