When the Abnormal Class was trying to obtain signatures from the faculty in order of use the Royal One as their classroom, Sabro was assigned to obtain Buer's signature. Initially Buer rejected his student assuming that a confrontation was imminent, and prepared to fight. Surprisingly Sabro bowed to his teacher and asked for forgiveness from his past actions, Buer, being moved by his students' actions remarked on how Sabro has matured and grown, eventually signing the Abnormal Class' petition.
Harvest Festival Arc
During the four-day Harvest Festival, Buer was the teacher assigned to take care and heal the students whom have withdrawn and were injured during the event.
Healing Factor - Blushenko's bloodline grants him the power to rapidly heal from any injury as long as he has mana, making him effectively immortal but doesn't stop him from feeling the pain of each attack.
Buer's impression of Sabro was initially negative due to the incident during the first day of classes, this however did change when Sabro demonstrated his willingness to seek for forgiveness and show respect towards Buer.
