The Wandering LEGO Dazai

Lego Dazai, who lives in Lego Yokohama City, transmigrates~

Cute as can be and without a brain, in a Lego world of three-head-tall figures with U-shaped hands, where you can pluck off your hair and head with a little pop, Lego Dazai is the third son of the Mori Company, and his family is truly 'happy.'

His eldest sister Akiko ran away from home because of her studies. His second sister Alice disappears if you so much as touch her. His rebellious younger brother Chuuya loves drinking and street racing, has no head, and often gets conned...

Lego Dazai considered himself the smartest and most reliable one in the family. His eldest sister Akiko joined a rival company, his second sister Alice kept getting their father, Mori, arrested for being a pervert, and his younger brother Chuuya got reported for underage drinking and street racing. Yet Dazai had never once given Mori a reason to worry when attending children's classes.

That is, until his friends were exposed:

Ango, a corporate spy for the rival company who worked five jobs at once; and Oda Sakunosuke, a former cold-blooded hitman and a wanted criminal listed at the police station... Their background checks failed, and they were all fired.

"Waaah, Dazai, you can't abandon your papa! They're bad kids. You'll turn bad if you hang out with them, waaah..." Lego Mori Ougai sobbed, clinging to Lego Dazai.

Lego Dazai 'coldly' pushed him away and shouted back, "No, I won't! Ango just likes working, and Oda Sakunosuke only tried being a hitman to get material for his writing. You're the one who's prejudiced against them!"

Unable to agree, Lego Dazai angrily ran away from home, only to have the bad luck to transmigrate. In another world, he encountered all sorts of alternate versions of himself...

P.S. I wrote a blurb.
