- "Now then... this might hurt juuust a bit, but it'll be alll right..."
- —Kind Doctor during the battle, Persona Q
Kind Doctor (優しいドクター) is a shadow in the series.
The guardian of the Evil Spirit Club, joined by the Calm and Caring Nurse. The three are performing an operation on a shadow before noticing the Persona users, with the Kind Doctor crushing the shadows head before turning his attention to the Persona users in order to begin an operation on them.
The Kind Doctor's in-battle monologue sounds as if he is progressing with a patient's checkup, preparing for an operation, and gradually starting to fail said operation. He declares the operation a failure on defeat.
The chest guarded by him contains a lock of hair. His dialogue near the end of the fight suggests that he is based on a doctor who performed surgery on Rei when she was alive, whose haunting words upon defeat suggest that she died.
The battle functions similar to the battle with Shadow Kanji in Persona 4, with the flanking assistants providing buffs and healing to support the boss. The Kind Doctor mainly performs physical attacks, so getting a Strength Bind or Fang Smash on him will sharply weaken him despite the nurses' buffs. If he prepares a Power Charge and is unbound, prepare to defend as he might follow with Drastic Measure that's likely to take out one party member.
Like the other bosses before it, the Kind Doctor and his nurses are susceptible to ailments. Poison will not only speed up the battle but also distract the red nurse into applying Diarama every now and then to the Doctor instead of spreading ailments among the party.
Having both protagonists in the party will be helpful as they can dispel the blue nurse's buffs and debuffs with Dekaja and Dekunda.
The Kind Doctor and his labyrinth represents Rei's feelings towards her life after discovering she had a fatal illness, specifically the realization she would never be able to go to school and is forced to stay in the hospital until she passed away; this is why the first half of the labyrinth is a school and the other half is a hospital (and to make them fit in the same labyrinth, the labyrinth itself took the form of a haunted attraction since both schools and hospitals have scary stories about them). The Kind Doctor mirrors Rei's hatred in being stuck in the hospital and represent the doctor responsible on taking care of her and failing to save her during the operation. The Kind Doctor's words during the battle until his defeat symbolizes the seriousness of Rei's illness and her death. The blood on his clothes can also symbolize Rei's death.
Like other boss Shadows in the series, the Kind Doctor and his dungeon embodies the reverse form of an Arcana, specifically the Hanged Man. The reverse Hanged Man means that one cannot make any decision and go forward in life. Thus, the Kind Doctor is someone who is overestimating himself, making him take his actions too lightly even if his patient has a serious illness, and becomes horrified & shocked easily when events start taking a turn for the worse (like during battle, he panicked when he said his patient's condition was getting worse after he had said that he was a famous surgeon; and said the operation failed miserably in a shocked tone upon his defeat). The end of the labyrinth, where the Kind Doctor's operation room is, has people being hanged from the ceiling in the background, representing the Hanged Man Arcana. The horror theme on the labyrinth may also represent the Hanged Man Arcana since normal people consider it a scary Arcana (since they don't know the true meaning behind it) and it can consider something to do with life or death situations, which applies to horror-related events (whether real life ones like war or fictional ones like monsters). Another connection between the labyrinth and the Hanged Man Arcana is the actions of the people (like Rei, the doctor, the nurses, and any other additional people) which would decide if Rei will be able to go to school or be forced to stay in the hospital forever.
