Rentaro has a plan to break the ice between Hakari, Karane, and Shizuka, and it involves laughter and Old Maid. But things take a turn for the unexpected.
It's the quietest burst 
of laughter ever recorded.
إنّه أهدأ ضَحِك انفجاري تمّ تسجيله في التّاريخ
Kille!
Le rire qui respecte le mieux
le voisinage.
Una risata fragorosa
che non disturba chi le sta intorno.
É a risada mais agradável
aos vizinhos da história.
Первый раз вижу,
чтоб так тихо разрывало…
