Iroha invades!

Iroha, color magic

After Naoki ran away

Reika, visit

The value of a man

The unknown boy

A victim from the future

Time diver

Human illustration

Come on, at least act macho!

The form of a heart, the form of a human

Humanoid machine

The final battle in the amusement park

Demon lord, infiltrate

Silence, and then

Changing world

And the future...

Not particularly good at sports, not very popular, and not very good at school, Naoki's middle school years are filled with video games and erotic books. But one day, a cute girl called Iroha appears, claiming to be his daughter from 20 years in the future. Apparently, in the future magic has been discovered, and she has come back in time by magic to protect her beloved papa from a dark future.
