Commence Castle Siege (攻城戦開幕 Kōjō-sen kaimaku?) is the hundred forty-fifth chapter of the Dandadan manga series.
Summary[]
Momo figures taking on the massive army would be impossible but finds out from the instructional scroll that they are able to build their own army using three dice conjured up. Having calculated the army to be roughly about 600 knights, Momo and Unji aim to match the number and start off with the blue dice that multiples the landed number by one. To assure her success in landing on six, Momo uses her powers to control the dice but ends up not having her roll count after the game detects her of cheating, much to Unji's disappointment. Momo then tries her hand at rolling the red dice that multiples the landing number by ten and ends up landing on one. Believing that he can manage to get a better number than her, Unji rolls the yellow dice that multiples the landed number by a hundred and ends up landing on two, which Momo was not pleased with. After building up an army of 210, Momo and Unji are instructed to assign each of their fighters with one out of the four roles: knights, archers, mages, and warriors. Momo and Unji decide to divide their troops equally into four types and give themselves roles as well, with Momo being a mage and Unji being a knight. After this is done, Momo and Unji become set to charge into battle with their troops. With the opposing army firing a myriad of arrows to rain down on them, Momo commands her army to raise up their shields but sees that the mages are taking damage due to them being weak against archers. Seeing the opposing army's front lines being made up of knights, Momo has her warriors fight against them, due to warriors being strong against knights, and has her archers ready for a counterattack after figuring that the opposing army will send in their mages to deal with the warriors.
