Adopted by a Mecha Girl? Mecha Girls Are Mothers Too!

Dean: "Lin Lu, you're a new student who just enrolled. How do you know how to repair an S-rank mech?"

Lin Lu: "My mom taught me."

Dean: "Then how do you know how to pilot an S-rank mech?"

Lin Lu: "My mom taught me that too."

Dean: "Huh?! Who exactly is your mother?"

Lin Lu: "You might not believe me, but my mom is an S-rank mech."

Dean: "Lin Lu! This is a Mech Academy, not a mental hospital!"

Lin Lu smiles faintly. "Dean, do you know... a mech girl is a mom too!"

What Lin Lu later takes pride in is that after she transmigrated, she was adopted by three mech girls.

One mature mech girl, one teenage mech girl, and one little-girl mech... Perfectly spaced in an arithmetic sequence!
