Suugaku Girl: Godel no Fukanzensei Teiri

A math enthusiast meets Milka, a brilliant student who challenges him with complex problems and elegant solutions, and they bond over discussions in the library. A year later, he begins helping Tetra, a younger student eager to learn math, as she slowly gains appreciation for its beauty. The third volume explores topics such as logic puzzles, Peano arithmetic, epsilon-delta definitions, Cantor's diagonal method, Hilbert's program, and Gödel's Incompleteness Theorems.
