Summoning: Quick Draw Oppression

Shintai after drawing his blood, swipes his arm at incredible speeds, releasing blade-like wave of wind that not only target(s) the enemy but also summons Hōganbiu; a human-sized, that snaps its massive claw [twice its own size], thus unleashing an extremely loud, high-pitched sound wave that exceeds 300 decibels that can essentially deafen the target, whilst they are being assaulted by the blade of wind. When its giant plunger slams into it socket, it displaces either air or water (depending on the medium) and creates a blast of pressure wave that can instantly create cavitation bubbles in the presence of water, the blast of pressure wave is strong enough to knock down hundreds of medium sized trees at once, but what makes this truly interesting is that when used under water, the moment after the bubble pops and releases the rather loud snap, the temperature climbs to a whopping 345000°F, though only for a moment. Even if one were to avoid the loud and extremely powerful pressure wave, they could still be boiled alive, if they are within range of this singing heat wave. Both in land and in water, the fast action of the claws snapping could indeed lead to the emission of a blinding light, that could act as additional distraction.

Trivia

 * Hōganbiu is able to deliver up to 640 Mpa in terms of sheer pressure by snapping its claws at just over forty thousand times the speed of sound.
