Going to post more later but here is some spoilers.

Noin's SS

Noin was level 3, age 16, and fought with a one-handed sword and a buckler shield. The SS took place in the dungeon during Vol. 3 when Astraea Record was fighting monsters on their way to the 18th floor with Ais, Riveria and Gareth. The SS mostly was just about her fighting position in battle with Astraea familia, but the most important part of the SS was that she told Ryu that she was putting too much strength into her shoulder. The same advice that Ryu gives Bell in volume 14.

Lyra's SS

(This is a summary, not a translation)

Lyra had no name. Her earliest memories was of being in a room with several other crying babies. One day a strange man in white clothes came into the room and started making a commotion. Other people came into the room to stop him. As Lyra watched him, suddenly she was splashed by a hot red liquid that flew from the man's body. The man's body collapsed, and the other adults dragged him out of the room. The commotion made all the other babies cry, but ever since Lyra was covered in the man's blood, she was completely silent. Lyra was wise and her only thoughts was of how she didn't want to get turned into the hot liquid that covered her like the man in the white clothes.

As time passed, Lyra started to notice that the adults, that would sometimes come into the room, would always take the babies that was located closest to the door outside the room. Once the babies were taken out of the room Lyra noticed that they never returned. Lyra assumed that this action would lead to the end of their lives. When the time eventually came that she was the nearest child to the door, she would in a box in the far corner of the room and try to ignore as other babies were taken in her place day after day. Lyra was able survive this way for quite a long time because she was very small even for a Pallum, which made it difficult for the adults to notice her correct age in comparison to the other children. Eventually as she grew though Lyra realized that she was reaching the limit of how long she could get away with it. Thinking this Lyra fearfully sneaked out of the room hoping no adults would find her. However when Lyra finally reached what she thought was the exit that would lead into her freedom, she instead entered a prison, the prison city Bergen.

To be continued later.
