I'm looking for two manga I saw a long time ago on a Blogspot.

The first one I seek most of all is about how a young boy discovers a gashapon vending machine, obtains a capsule, and releases a blue-skinned devil wearing a big hat from within.
NOT Yo-kai Watch!

The second one is about a reaper boy who falls in love with a bedridden girl... whose favorite book is Mein Kampf. She obtains his scythe using it backwards, hitting it like a bat, unleashing terrifying power.

I saw them around the same time as:
Blazer Drive(2008)
Antimagia(2011)
Dokusai Grimoire(2011)
Drc2(2011)
Kyokou no Ou(2011)
Ryuu wa Tasogare no Yume o Miru(2011)
Seigi no Mikata!(2011)
Servamp(2011)
Suashi no Meteorite(2011)

Please help!
