Chapter 100.5

At the Portway to the Sky, Part 9.5 (空ノ港二テ 其の玖 後編,) is the second part of Chapter 100 of the Bungo Stray Dogs manga.

Synopsis
There’s an unwritten rule in Yokohama: Don’t ever make Kenji angry. The fury of nature is unleashed and Tetchou realizes he’s bitten off more than he can chew!

Summary
Tetchō is hurled away by a menacing Kenji, who repeatedly voices his need to help out. Tetchō evades the detective's following attacks, wondering about the surprising gravity of the latter's ability. As the Hunting Dog attempts to strike him, Kenji catches his fist and and lands a fatal blow on him instead.

Back when Atsushi worked on his first fieldwork with Kenji, the erstwhile newcomer told Kunikida about other people's unusual kindness towards Kenji, which Kunikida linked to one of Yokohama's unwritten laws: to never make Kenji angry.

He then began to narrate how a certain farming village in the that suffered a destructive, remained almost unharmed in the aftermath. Fukuzawa found out then that Kenji had barehandedly changed the shape of a mountain that diverted the flow of the flood away from the village. However, Kenji's best friend was among the event's casualties, which the boy apparently ended up having no memory of.

Kunikida expounded that Kenji's ability is that of untamed nature, which is simply being contained in his mild demeanor. Such catastrophic disaster-like fury drives away Kenji's gentleness, hence compelling him to substitute that anger with the urgency of hunger. As Atsushi surmised what might happen if Kenji were to get enraged, Kunikida rhetorically asked Atsushi if there is one person in the world who can stop eruptions with their bare hands.

Back at the airport, the clobbered Tetchō urges Kenji to finish him off, ruing that he should have chased justice and thought things over calmly, especially realizing that Jōno would in no way ask him to abandon the mission for his sake. Admitting how he failed his friend and justice, as well as mistook his enemy, Tetchō deems himself unfit to be a Hunting Dog and prepares for his impending fate.

In truth, Kenji removes a column pressing down on Tetchō, reverts to his typical gentleness, and suggests to go look for the missing Jōno together. In the end, Kenji remarks that he has no need to pour his anger on the Hunting Dog and offers him a helping hand. Nevertheless, worn out from their fight, the two end up laying on the floor. Tetchō and Kenji soon introduce themselves to each other, with Tetchō declaring that knowing Kenji's name is his largest gain for the day, before the two eventually doze off.
