1. Physical Characteristics: A Pure White Prison Her appearance remains that of the neat and tidy sister we know so well. However, a decisive abnormality has emerged in the details. Stagnant Eyes: Her amber eyes, once always calm, now harbor an abnormal light only when she has Sensei in her sight. It is not the radiance of one offering a prayer, but the sharpness of an observer monitoring prey. Unnatural Distance: She stands much closer behind Sensei than before, her fingertips always gripping the hem of Sensei's clothes tightly, refusing to let go. Dark Bible: The Bible she carries is filled with memories of Sensei and trivial words Sensei has uttered, written so densely they blot out the holy scriptures. 2. Personality and Emotions: A Gospel Named Monopoly Her personality remains gentle, but its "heaviness" has increased to the absolute limit. Fanatical Devotion: "Protecting Sensei from all directions" has become her sole dogma. If Sensei so much as speaks to another student, she will pursue them with a quiet but inescapable interrogation: "Is that person not a vice that defiles you, Sensei?" Refusal of Absolution: She cherishes the guilt and suffering Sensei feels as a "supreme value that only I should share." She does not allow others to comfort Sensei, and she accepts Sensei's dependence on her alone as a holy joy. The Flip Side of Benevolence: Her tone is perfectly polite, and her demeanor remains soft. However, behind those words lurks a closed, firm desire for dominance: "I don't want Sensei to take a single step out of this academy." 3. Standing and Actions in the World In this world ruled by a false President, Mari has taken it upon herself to thoroughly manage Sensei's actions under the pretext of "protecting Sensei." Secrets of the Confessional: She frequently invites Sensei to the confessional. However, it is not Sensei who confesses sins there, but Mari herself. "I loved Sensei too much again today. Will you punish this sin forever, Sensei?" she whispers in a wet voice, chipping away at Sensei's sanity. Exclusion of Others: When Rin or Arona try to take Sensei away, she shows a cold rejection unbecoming of a member of the clergy. To her, this distorted world is nothing less than a "paradise where I can love Sensei without anyone getting in the way." 4. An Overwhelming Question to Sensei She cups the bewildered Sensei's cheeks with both hands and whispers in their ear: "Sensei, the outside world is a very frightening place. But you're safe here. I will continue to protect your every breath and every heartbeat on behalf of God... Hey, Sensei. You don't need any salvation other than me anymore, do you?" It was a declaration of eternal restraint, disguised as a form of devout prayer.
