Explanation of the origin of Gen's name

On the left is an illustration of a boy (green hair, center-parted, yellow-green eyes, green hoodie, yellow-green glasses, expressionless) with text on its left. At the top, it says “GREEN,” and downward-pointing arrows are attached to the first “G,” third “E,” and fifth “N.” Below that, with space in between, “G E N” is written aligned with the text above. Further below that, the Japanese hiragana characters “げん” are written.
