[Yamada Hideki] Manyuu Hikenchou Ch.13 (Vol.3 Ch.1) [biribiri]

Kaede's travel companion gets caught red-handed keeping a secret 'boobs growth record,' a running log of every inch gained since their first village together, much to Kaede's flustered horror. Flashbacks replay how it all began: a sister's breast-hunting crusade answered with a cleaving blade, an absorbed bounty, and an unfortunate girl taught the secret scroll's fondling technique for accelerating female hormones. Between vows to become the second 'Boobie Kid' and steal the breasts of villains like there's no tomorrow, a closing omake chart proves Kaede's assets are still slowly growing.
