This is canon btw.
" In fact, Makima's name when you use a chainsaw to cut away "ki" (the Japanese word for "wood" or "tree") becomes "Mama", Fujimoto-san himself revealed."
"I couldn't draw it in the final episode, but it would be a little messy if I drew it. I didn't draw it, but uh, the chainsaw is a tool for cutting trees, and when I cut a chest of drawers (tree), It became a mama, and what Denji was always seeing on Makima wasn't romantic love but motherhood. I named her Makima because I wanted to make it understandable."
