Chapter 13.3 is the third part of the 13th chapter of the Bungo Stray DEAD APPLE manga.
Summary[]
Tsujimura is in awe towards Chūya's ability; Ango expounds that it is a gravity manipulation ability, though tapping into his Corruption state does not allow him to control his power or to disable it. Tsujimura then surmises that the only way to stop him is for him to die, to which Ango regrettably tells her that Dazai's nullification ability is their only known method of stopping him that works.
Meanwhile, the dragon emits a light beam from its mouth, diffusing into various smaller dragon-shaped beams towards Chūya, who deflects them with his gravity manipulation. As a swarm of dragon beams envelop him, Chūya blasts them off and summons a massive graviton, then hurls it towards the dragon. In turn, the latter summons another gigantic beam of light, which sends Chūya flying away in the impact.
