Raziel

Raziel's Ascension Ability didn't change too much in nature, but the way it manifested has practically reversed entirely. In the past, she, as a Citadel mentor, maintained a conservative and cautious attitude toward Ascension Abilities. "Mind Walk," which was used to analyze one's thoughts and feelings, was hardly ever utilized by her even though it could make a simple conversation smoother. Now, however, as an Angel, Raziel would unhesitatingly turn endless thoughts and feelings into torrents and use them on the battlefield. Due to that, she would appear especially frenetic during combat as all sorts of thoughts and feelings engulf her.
After Raziel processed and obtained sufficient data and embodied thoughts — commonly known as "crystallization" — from Unbewusstes, her mental state stabilized, and part of her appearance was also returning to its former humanly state. But as of now, the odds of her body completely returning to normal are exceedingly low, much less her psyche and memory.
In any case, she has changed, but she's also growing and recovering bit by bit, slowly learning the knowledge of this world and becoming a new "person." Facing such a child, who could possibly criticize her?

Lissandra, Dustin, and other old acquaintances of Raziel have provided substantial assistance in her recovery and readaptation. They all behave with extreme caution toward Raziel, particularly Lissandra, who keeps avoiding meeting this former friend of hers in person. Lissandra might not have ever verbalized it, but her behavior makes it adequately clear: She believes the current Raziel is an entirely different entity and therefore has no need to inherit Raziel's previous life and relationships.
However, Raziel herself has a different perspective. As her understanding of the surrounding world deepened, she started having a myriad of questions and also began wondering about her past. "What was life like for Raziel?" "What kind of person was she?" These questions aren't easy for others to answer. Hence, she has chosen to seek them herself in daily life and in every matter that's relevant to the past.

Her search will never end. Just like any child that is born in the world, she is presently walking her own path that nobody can do in her stead. That said, as friends and companions, the Eternal crew can provide her with appropriate guidance and company. I implore you all to do so, and I believe you will.
— One of Lissandra's letters, archived

"I am simply here to deliver some books. Although I picked them based on my preferences, she should probably... You all can read them too. For Raziel, these books should be perfect for her need to relearn the world."
"Got it. But won't you say something to her?"
"No need."
"All right. We will pass them to her. Please rest assured, Ms. Lissandra."
Right as Livia accepts the few books Lissandra hands over, the carriage door behind them opens. The executor in red turns around and happens to come face to face with Raziel, who's entering the carriage.
In her quest to relearn herself and the world, Raziel finally made it here. She has chosen to personally meet this person who has given her lots of gifts, this friend of the old Raziel, albeit to her, they have never met until now.
"Hello. ...Are you Lissandra?"
"Yes."
"Were we friends?"
"...Yes."
"Then can we be friends again?"
"Of course. But that is entirely up to you. Should you not want to —"
"I want to get to know you and many, many others." Raziel flashes a genuine smile. "It's a pleasure to meet you, Lissandra."
Once again, the new Raziel extends her hand toward "her" old friend and her brand new life.
