Synopsis
Shalsha reiterates that any magic that Azusa uses will have no effect on her, Azusa tries to cast another spell, but its extinguished by Shalsha. Falfa then details that Shalsha has culminated mana for 50 years just for that moment in time. On the other hand, the mana consumption to use Haja Magic is great and Shalsha has at least an hour or two before she runs out of it. Noting how bad the efficiency is for the magic, Azusa asks why Falfa doesn't resent her, which Falfa reveals its because she's alive because of her. Honestly, Falfa wanted meet Azusa sooner, but was stopped by Shalsha whenever she tried. When she finally did, however, she was overjoyed by them finally being able to meet. Just as the two enjoy a moment with each other, Shalsha stops them and prepares to attack. Trying to flee the scene by using flying magic, but Shalsha erases the magic causing Azusa to fall into the ground. After Shalsha openly declaring her goal to kill Azusa for killing so many slimes over the years. Azusa concedes that her end is neigh and says her goodbyes to Falfa and Laika. Not wanting her master to die, Laika transforms into her dragon form and faces off against Shalsha and with a light kick KOs her.

Afterward inside one of the newly created rooms in Azusa's home, Shalsha is seen resting in a bed. Falfa states how her sister only focusing on a magic that solely focused on defeating Azusa was a major flaw as it leaves her vulnerable to other opponents. This is also corroborated by Laika, pointing out how Shalsha's Haja Magic was only effective against Azusa. Just then, Shalsha awakens and immediately tries to use magic against Azusa, but doesn't have any mana left over and won't have enough to use any of her Haja Magic for decades. Reflecting on how her sole purpose was to defeat Azusa and now her purpose has been jeopardized. Therefore, Azusa puts a positive spin on it stating that if she died, Shalsha would have lost her purpose for living, and Shalsha reluctantly agrees. Chiming in, Falfa details that since Shalsha was passed out Azusa has been taking care of her using her extensive medical knowledge. Curious as to know why Azusa would do such a thing, Azusa answers it's because she's her mother. Tearfully, Shalsha doesn't deny the fact, but reinforces that she's still an enemy of all slimes. Falfa then states that humans and slimes will always fight and even if Shalsha killed Azusa, humans would still continue killing slimes and convinces Shalsha to turn over a new leaf. When Azusa asks where the two will return, Falfa states they'll return to their cabin in a forest, where no one ever bothers them. Offering a counter offer, Azusa offers the twins to stay at her home and convinces Shalsha to call her "mother" instead of her moniker.

A monologue reveals that Azusa accepted the girls not because of her guilt, but because they needed a mother figure in their lives. Now contrary to her single leisurely life, Azusa has now let into her life a disciple and twin slime spirits. Life seemed to continue once again with peace and leisure, that is until a lone elf on the run trips and falls cries for help to the Witch of the Plateau.
