He was born as Michael Rieveldt, but assumed his mother's name after he cut ties with his father following.
Michael is a straight-laced devoted soldier. He is considered both professional and loyal.
Michael Rieveldt is a son of the Vice-President of the Rieveldt Company. They were always very close to the other Rieveldt family until the accident that took the lives of Claire's father, mother and little brother. After that Claire was taken in to their family and Michael was a reliable older brother to Claire.
After Michael's father got caught in a practice of scamming, Michael and his mother discarded the name "Rieveldt" and took back his mother's family name "Irving" and so they cut ties with the incident.
Joining the Military Police
Michael joined the Railway Military Police around the same time as Claire Rieveldt, whom he considers a rival at heart. Michael is very strict with Claire and that is his slightly awkward way of being concerned about his adoptive sister.
Erebonian Civil War
Transfer to Thors II
The real purpose behind Michael's transfer to Thors Branch Campus is twofold. First, he is to monitor the principal and former provincial army commander Aurelia Le Guin. Second, he is responsible for using the classes of the school as counter-measures against the possible actions of Ouroboros and the Jaegers, of which he possesses special intelligence.
- In Dengeki PlayStation 536, Falcom president Toshihiro Kondo comments that "Michael Irving is a real military man [...]". The only other appearance of the name "Irving" in the series is in Moon Door 2 of Trails in the Sky The 3rd, where General Morgan's son and daughter-in-law, Irving and Rachel, are in the final month of the pregnancy of their soon to be born child, Rianne. In Trails in the Sky FC and SC, Rianne lives with her grandparents in the City of Grancel while her parents are unmentioned. It is believed that Major Michael is the father of Rianne and thus the son of General Morgan. Neither Famitsu nor the official Trails of Cold Steel III website, however, mention the name "Irving".
