ALL OF THIS WILL LIKELY CHANGE...
AFTER THE WAR
→ Roughly 28.
→ Kept the final version of each of the OT4's uniforms after the war ended (Allen's, of course, is the third version he left behind). They're tattered, torn and bloodstained. She stores them in a box in the very back of her closet and hasn't looked at them since the war ended. Her golem (disconnected) is hidden there, too.
→ Lives with Komui in a small townhouse in whatever town they ended up moving into. He spends most of his time tinkering with small machines and sleeping; she cooks and wanders town.
→ Works in the summer and fall picking fruit; usually smells like canning.
→ She keeps in touch with Bak via letter. He's doing much better about his hives.
→ Divides her time pretty evenly between her own, Allen's and Kanda's houses. Since Allen does Kanda's (healthy) grocery shopping for him, she brings him things like seedlings for his garden, books she thinks he might like, the occasional soba stash, and anything that she thinks he might run out on between Allen's grocery runs. Once a week, she visits Allen's house and shares the highlights of her week with him- including her brother's shenanigans, word from other Order members scattered across the globe, and anything interesting goings-on from around town.
PHYSICAL CONDITION
→ Between she, Kanda and Allen, Lenalee is probably in the best physical condition. That said, there are lingering reminders of the strain the war took on her; high heels hurt to wear for any extended period of time and flats strain her hamstrings because she's so used to heels.
→ Had Hevlaska remove her anklets for her some weeks after the last Akuma were eradicated. The process was more detrimental to her health than it had been, say, when her Boots were removed after the Ark. With the Innocence attached to her blood as it was, once removed, she suffered from mild hypovolemic shock for several weeks following. She occasionally gets an intense pins-and-needles sensation in her legs and the cross-shaped scars remain on both ankles.
→ Developed mild
knee osteoarthritis in her early twenties thanks to using her legs as a weapon of war for the majority of her life.
→ Still "tiny". Pretty much reached 5'6 and stayed there.
→ True to Anita's wishes, she hasn't cut her hair once since it burned off on the trip to Edo. It's now close to mid-thigh. God only knows how she keeps it under control.
MENTAL CONDITION
→ I DON'T... KNOW. SUBJECT TO RADICAL CHANGE AND/OR EXPANSION.
→ She's pretty much irrevocably stuck in the mentality of "other people could become an enemy just like that" despite knowing full well there are no more Akuma in the world. It's just something she's been conditioned into. Though she knows most of the people around town and is on good terms with them, she has woefully few ties to anyone outside the Order even now.
→ As a result of the above, she is to remain... eternally single. Part of her is disappointed in herself.
→ Though you'd never know it by looking at her, she's extremely terrified of the day that Allen and Kanda finally die. It's a constant, low hum in the back of her mind- and while she tries not to let it become the main focus of their time together, part of the reason she spends so much time visiting them both is because she doesn't know how soon it will be before she's visiting their caskets instead.
→ Despite the fact that she requested Hevlaska remove her Innocence, she still misses flying and misses that never-die feeling her Boots gave her. It's hit her hard that now she can't always be counted on to beat the clock and get to someone on time in a do-or-die situation. That there's new dangers in heights and falling that she never had to think about before. She doesn't have the fallback option of invocating and has no idea how to cope with that.
