In 1925, Kirsimägi won first prize with his abstinence-related work "Kõige parem võitlusviis alkoholi vastu Eestis" (The Best Way to Fight Alcohol in Estonia)—but he had given up abstinence before receiving the award.

The fraternal organization Korporatsioon Sakala issued a blacklisting decision (Estonian: rukk) against him.

[9] He appeared in the Estonian feature film Esimese öö õigus (1925), in which he jumped into the water from Tartu's Stone Bridge.

Kirsimägi published the first and so far the only corporatist novel in Estonian literature, Puhastustuli (Purgatory), which won first prize at the Nature Novel Competition [et] in 1929.

In 1933, Kirsimägi committed suicide by gunshot after shooting and wounding Bruno Madisson (1904–1943) and his wife Ilse (née Aluhn, 1909–1991), in whom he had a love interest.
