Overall, the OVA of Hoshizora e Kakaru Hashi lived up to my expectations. Even though they weren't very high.
The story is fairly a simple one, as most are in this genre. Instead of Kazuma taking the spotlight of the lead character, the attention is shifted to Daigo. The entire episode is essentially Daigo looking for a girlfriend. However, this plot line allows for a more comedic approach, and more fanservice, which both appeal to those who were originally interested in the original series.
The art is that of the quality of the main series. Nothing to extravagant.
No new OP or ED in this
OVA, however there is one insert song that some may find appealing.
This OVA allows for more character expansions on Daigo, which I believe they did a good job with. However, some may not like Daigo as a character. If you're one of those people, this OVA is not for you.
I really enjoyed this OVA on a personal level, as I enjoyed the original and only recently found out about this OVA.
Overall I would rate Hoshizora e Kakaru Hashi OVA as a 7, as it lives up to expectations, but does not however go past that line and impress. If you're a fan of the original series, this OVA is for you.
