Rei Todoroki

Shouto's Mother is Shouto Todoroki's mother.

Appearance
She is a very beautiful slim young woman with long white hair.

Personality
Shouto's mother was kind, caring and loving towards Shouto and in return Shouto loved her deeply. She would always support Shouto such as trying to stop her husband's mad training methods and encouraging Shouto to become the man he wants to be, indicating her selflessness. However, the constant abuse that she received from Endeavor caused her to become mentally unstable and this was the cause of why she burned his face (she did not do this out of hatred for Shouto but rather from her insanity).

History
Shouto's mother had always been abused by her husband Endeavor. When Endeavor began to train Shouto when he was five which was harsh and detestable, she would intervene, trying to stop Endeavor's mad training methods but only to fail. She always supported Shouto in these dark times, saying to him that its okay to become a hero, telling him that he is not a slave to his bloodline and that he can become the man he wants to be.

Soon, she became insane from all the abuse by Endeavor and started to hate him as well as Shouto's left side (both face and Quirk). She finally snapped and threw boiling water over Shouto's face, causing a burn over his left eye. However, Shouto bore no ill will against her for this incident and showed no hatred for her. Later, it was said by Endeavor that she was admitted to hospital because of the incident.

Sports Festival Arc
The next day after the end of Yuuei's Sports Festival, Shouto goes to the hospital where his mother is to see her. Shouto opens the door and enters her room. Shouto's mother sees her son.

Field Training Arc
It was shown that after Shouto's visit, she apologized in tears to him as she smiled at him and forgiven him as well. She then told him that she was happy as she was saved if he pressed forward without holding back.

Quirk and Abilities
Ice Quirk: A Quirk that gives her a power related to ice.

Endeavor
Endeavor is her husband. However, the relationship between them is not a loving one. She started to hate Endeavor for making Shouto go through detestable training and tried to stop him but only to fail. Her hatred for him would become worse when he started to constantly abuse her. Her hatred for him, along with the constant abuse by him, would cause her to become insane and a result led her to throwing boiling water over Shouto face as his left side reminded her of Endeavor.

Shouto Todoroki
Shouto's mother was a kind, caring and loving parent towards Shouto unlike Endeavor. She tried to stop Endeavor from making Shouto go through his detestable training for Shouto's sake. During these dark times, She would constantly support Shouto, saying to him that he isn't a slave to his bloodline and encouraged him to become whatever he wants to be. However, her hatred for Endeavor along with his constant abuse towards her would cause her to go insane and finally snapped when she threw boiling water over Shouto's face (although, it should be noted that she did this out of spite for Endeavor and not because she hated Shouto).

Quotes

 * (To her mother) "Mom...I know it's not right, but I can't do it anymore. The children, they're...like him more and more every day. And Shouto...his left side. Sometimes I look at him and hate what I see. I...can't raise him anymore. I shouldn't raise him..."
