Only after having fun in Hisashi’s room in an all-nighter did Seiji finally leave with satisfaction.
At first, Kaede came to play with them as well, but she fell asleep as she played, so Hisashi unhesitatingly called for the maids to take his sister away while they continued playing on his game systems.
So this otaku wasn’t a sis-con…
After spending the night at his house, Seiji learned that besides being a true otaku, Hisashi was also a sharp investor. All of Hisashi’s otaku products were purchased with money earned by himself through the stock market with risky investments such as futures.
His family only provided him with some initial funds which he had returned with interest long ago, and he was now allowed access and control over half of the Juumonji group’s total funds.
